Question

Use your knowledge of special cases to solve the problem.

Answer 1

Answer:

C

Step-by-step explanation:

We want to simplify:

$(3a-2b)^2$

Recall the perfect square trinomial pattern:

$(a+b)^2=a^2+2ab+b^2$

Let a = 3a and b = -2b. Thus:

$(3a-2b)^2=(3a)^2+2(3a)(-2b)+(-2b)^2$

Simplify:

$=9a^2-12ab+4b^2$

Our answer is C.
