Question

$$4 a - 7 a b + 3 b + 12 12 a - 9 a b + 5 b - 3$$

Evaluate

$-16ab+148a+8b-3$

Solution Steps

Multiply $12$ and $12$ to get $144$.

$$4a-7ab+3b+144a-9ab+5b-3$$

Combine $4a$ and $144a$ to get $148a$.

$$148a-7ab+3b-9ab+5b-3$$

Combine $-7ab$ and $-9ab$ to get $-16ab$.

$$148a-16ab+3b+5b-3$$

Combine $3b$ and $5b$ to get $8b$.

$$148a-16ab+8b-3$$

Differentiate w.r.t. a

$148-16b$
