👉 Learn how to write polynomial equations given the zeros of the polynomial. When given the zeros of a polynomial, the first thing that we do is to set the given zeros individually equal to the same variable and then we take the zero to...

Learn how to add/subtract rational expressions with trinomials in the denominator. When adding or subtracting two or more rational expressions with common denominators, we add or subtract only the numerator while we keep the denominator...

Tutorial - Complete Multiplying and Dividing Rational Expressions

👉 Learn how to solve proportions. Two ratios are said to be proportional when the two ratios are equal. Thus, proportion problems are problems involving the equality of two ratios. When given a proportion problem with an unknown, we...

We solve a literal equation just like any other equation. When we solve for a variable we need to isolate the variable meaning we need to undo the operations that are being applied to the variable. Make sure you apply the inverse...

In this video series you will learn multiple math operations. I teach in front of a live classroom showing my students how to solve math problems step by step. My math tutorials should be used to review previous lessons, complete your...

In this video playlist I show you how to solve different math problems for Algebra, Geometry, Algebra 2 and Pre-Calculus. The video will provide you with math help using step by step instruction. Math help tutorials is just what you need...

Learn how to compose two functions where one or both of those functions is/are quadratic. To compose two functions means to express one of the functions as a function of the other function. This is done by replacing the input variable of...

👉 Lean how to divide rational expressions with a radical in the denominator. To divide rational expressions with a radical in the denominator, we rationalize the denominator by multiplying both the numerator and denominator by the...

👉 Learn how to add or subtract radicals. A radical is a number or an expression under the root symbol. Radicals can only be added or subtracted if the numbers or expressions under the roots are the same for all terms. To add or subtract...

This is a quick whiteboard tutorial that explains binary shifting and how to do it for both the multiplication and division of binary numbers.

Divide a whole number by a fraction.

Understand how the placement of the decimal point changes when multiplying decimal numbers by powers of 10.

In this video, we explore what equivalent fractions are and why they are useful. We also learn different ways to find equivalent fractions, including using models and a fraction chart, as well as multiplying or...

In this lesson, students will learn about the associative property of multiplication by using the volume formula. They will understand that the order in which they multiply the dimensions of a rectangular prism does not affect the final...

👉 Learn how to multiply polynomials. To multiply polynomials, we use the distributive property. The distributive property is essential for multiplying polynomials. The distributive property is the use of each term of one of the...

In this video playlist I show you how to solve different math problems for Algebra, Geometry, Algebra 2 and Pre-Calculus. The video will provide you with math help using step by step instruction. Math help tutorials is just what you need...

👉 Learn all about evaluating trigonometric functions with triangles. In this playlist, we will learn how to evaluate, sine, cosine, tangent, cotangent, secant, and cosecant when given the sides of a triangle. If we have missing sides we...

👉 Learn how to graph a cotangent function. To graph a cotangent function, we first determine the period (the distance/time for a complete oscillation), the phase shift (the horizontal shift from the parent function), the vertical shift...

👉 Learn how to apply the rules of exponents to simplify an expression. We will focus on applying the product rule, quotient rule as well as power rule. We will then explore multiple properties such as power to product, power to quotient...

Subtract two rational expressions

👉 Learn how to factor polynomials by GCF. A polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. To factor an algebraic expression means to break it...

👉 Learn how to multiply radicals. A radical is an expression or a number under the root symbol. To multiply the sum/difference of two or more radicals, we make use of the distributive property to expand the product and then simplify the...

👉 Learn how to simplify complex fractions. To simplify complex fractions having the addition/subtraction of more than one fractions in the numerator or/and in the denominator we first evaluate the numerator or/and the denominator...
