What is CUBE OF A BINOMIAL ? Give me some examples and show the solution

Sagot :

 The cube of a binomial is when a binomial is multiplied by itself. For example:
 (3x+x)²
Sol'n:
(3x+x)²

Add the similar elements.
3x+x = 4x.

(4x)²

Apply the exponent rule:
4²x²

Solve.
16x²

binomial has 2 terms, a term will be counted by dividing the two by sign

(5x+8)²
