👉Learn how to solve a quadratic equation by factoring out the GCF. When factoring out the GCF from an equation we will be looking for what the terms have in common. This method is very useful for quadratic equations that does not have...

👉Learn how to solve quadratic functions. Quadratic equations are equations whose highest power in the variable(s) is 2. They are of the form y = ax^2 + bx + c. There are various techniques which can be applied in solving quadratic...

👉 Learn how to classify polynomials. A polynomial is an expression of the sums/differences of two or more terms having different interger exponents of the same variable. A polynomial can be classified in two ways: by the number of terms...

👉Learn how to factor quadratics. A quadratic is an algebraic expression having two as the highest power of its variable(s). To factor an algebraic expression means to break it up into expressions that can be multiplied together to get...

This video discusses on conversion between types using C++ casting operators. This clip is from the chapter "Operator Overloading" of the series "Complete Modern C++".This section is about overloading and type conversion.

👉 Learn how to find the missing measure of a segment. A segment is a line that has two endpoints. A segment can be subdivided into several portions. The length of the segment is the sum of all the sub-divisions of the segment. Thus, when...

👉 You will learn how to multiply integers from one digit to multiple digits. When multiplying it is important to understand that multiplication is just repeated addition. However with multi-digit numbers we will follow a step by step...

Collocations are groups of words that they usually go together. There are seven groups of collocations. In this video lesson, Mr. P. will explain every pattern and will give examples for each. He will list collocations with HAVE, MAKE...

In this video you will learn the difference between the words #well and #good. It will give you easy examples. This lesson is addressed to the beginner student who wishes to learn English grammar, but also to advanced students who need...

This is a tutorial on how to factorize simple quadratics. They define quadratic equations as equations or expressions where the highest power of the variable is 2, and explain that factorizing is the reverse of expanding the brackets....
