What are the perfect square trinomials?

Answers

A perfect square trinomial is

(square of one term) + (square of another term) + (double the product of the two terms)

Let's look at the following trinomial.

X² - 14x + 49

(x - 7) (x - 7)

(x - 7)²

This trinomial would be classified as a perfect square trinomial because it factors as two identical binomials which is (x - 7)². This means that any trinomial that factors as two identical binomials is called a perfect square trinomial.

Which expression is equivalent

Answers

Answer:

a^9*b^6

Step-by-step explanation:

a^(-8) b 1 1

-------- = a^(-3), and ----------- = --------- Their product is --------------

a^(-5) b^(3) b^2 a ^3*b^2

This is the algebraic expression inside the parentheses. We must now take

the negative 3rd power of this result.

(a^3*b^2)^3 = a^9*b^6
