Question

. Given a = 2 and b = -3, evaluate the expression given below. a²b + ab + b² A) - 9 B) -15 C) 3 D) 27

Answer 1

We have the following expression:

$a^2b+ab+b^2$

By substituting a=2 and b=-3 into this expression, we have

$(2)^2(-3)+(2)(-3)+(-3)^2$

which gives

$\begin{gathered} (4)(-3)-6+9 \\ -12-6+9 \\ -18+9 \\ -9 \end{gathered}$

Therefore, the answer is option A: -9
