$(6 c^{2} - 2 c - 1) + (- 4 c^{2} + 7 c + 5)$

Step 1

Remove parentheses.

$6 c^{2} - 2 c - 1 - 4 c^{2} + 7 c + 5$

Step 2

Subtract $4 c^{2}$ from $6 c^{2}$ .

$2 c^{2} - 2 c - 1 + 7 c + 5$

Step 3

Add $- 2 c$ and $7 c$ .

$2 c^{2} + 5 c - 1 + 5$

Step 4

Add $- 1$ and $5$ .

$2 c^{2} + 5 c + 4$
