Rational Expressions | Preparing for Precalculus Part 5

👉 Learn how to simplify rational powers using the power and the quotient rules. There are some laws of exponents which might come handy when simplifying expressions with exponents. Some of the laws include the quotient law which states...

👉 Learn about Descartes' Rule of Signs. Descartes' rule of the sign is used to determine the number of positive and negative real zeros of a polynomial function. Knowing the number of positive and negative real zeros enables also to also...

Learn about simplifying rational expressions. A rational expression is an expression in the form of a fraction. To simplify a rational expression is to put the expression in a simplified form i.e. cancel out common factors, etc. When...

👉 Learn how to divide polynomials using the long division algorithm. To be able to solve a polynomial, we need to be able to get the factors and hence the zeros. To get the factors, we use the rational zeros theorem to get one of the...

👉 Learn how to divide polynomials by a monomial using the long division algorithm. A monomial is an algebraic expression with one term while a polynomial is an algebraic expression with more than one term. To divide a polynomial by a...

👉 Learn how to simplify complex fractions. To simplify complex fractions having a fraction as the numerator and another fraction as the denominator we first factor the expressions that can be factored and then we multiply the fraction in...

Write simple numerical expressions that replace verbal statements of arithmetic.

Lucca and his four friends went to a fair. There, Lucca purchased a one fourth pound fudge. If he plans to split the fudge evenly between his 4 friends and himself, how much fudge will each person get?

Extend the concept of division of two whole numbers that yield no remainder into any two whole numbers.

Sally and her friends want to buy 8 cheeseburger meals. They have $80, and each meal costs $9. Do they have enough money to pay for the meals? And if there is any money left over, how many milkshakes can they get, if each costs $2?

In this short video we will answer a standardized math test question where we are asked to identify the equivalent expression. We will review how to divide by a fraction using the rule multiply by the reciprocal or also known as keep,...

Master Simplifying an expression using the quotient rule of exponents

👉 Learn how to find all the zeros of a polynomial given one rational zero. 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. The zeros of a...

👉 Learn how to solve quadratic equations by completing the square. When solving a quadratic equation by completing the square, we first take the constant term to the other side of the equation and create a perfect square trinomial with...

👉 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...
