Simplify (8a^2-6-8a)+(1-6a-7a^2)

$(8 a^{2} - 6 - 8 a) + (1 - 6 a - 7 a^{2})$

Step 1

Remove parentheses.

$8 a^{2} - 6 - 8 a + 1 - 6 a - 7 a^{2}$

Step 2

Subtract $7 a^{2}$ from $8 a^{2}$ .

$a^{2} - 6 - 8 a + 1 - 6 a$

Step 3

Add $- 6$ and $1$ .

$a^{2} - 8 a - 5 - 6 a$

Step 4

Subtract $6 a$ from $- 8 a$ .

$a^{2} - 14 a - 5$
