Question

Simplify and then evaluate the equation when A=2 and b=4

Answer 1

we have the equation

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

Remove the parenthesis and apply the distributive property

$b^2+3b-3b^2-2a$

Combine like terms

$-2b^2+3b-2a$

For a=2 and b=4

substitute

$\begin{gathered} -2(4)^2+3(4)-2(2) \\ -32+12-4 \\ -24 \end{gathered}$

the answer is -24
