$16 c^{2} d - 4 c d^{2} + 5 c d + (- 12 c^{2} d - 4 c d^{2} + 7 c d)$

Step 1

Remove parentheses.

$16 c^{2} d - 4 c d^{2} + 5 c d - 12 c^{2} d - 4 c d^{2} + 7 c d$

Step 2

Subtract $12 c^{2} d$ from $16 c^{2} d$ .

$4 c^{2} d - 4 c d^{2} + 5 c d - 4 c d^{2} + 7 c d$

Step 3

Subtract $4 c d^{2}$ from $- 4 c d^{2}$ .

$4 c^{2} d - 8 c d^{2} + 5 c d + 7 c d$

Step 4

Add $5 c d$ and $7 c d$ .

$4 c^{2} d - 8 c d^{2} + 12 c d$
