Question

w.11 multiply polynomials 58a
find the square. simplify your answer.
$(3s - 3)^2$

Explanation:

Step1: Use square of difference formula

Recall $(a-b)^2=a^2-2ab+b^2$, here $a=3s$, $b=3$.

Step2: Calculate each term

First term: $(3s)^2 = 9s^2$
Second term: $2\times3s\times3=18s$
Third term: $3^2=9$

Step3: Combine terms per formula

$(3s-3)^2=9s^2-18s+9$

Answer:

$9s^2 - 18s + 9$
