# How do you simplify 6b - 4 – 5b^2 – b^2 – 7?

Mar 12, 2016

$- 6 {b}^{2} + 6 b - 11$

#### Explanation:

Collecting like terms

$\left(- 5 {b}^{2} - {b}^{2}\right) + \left(6 b\right) + \left(- 4 - 7\right)$

$\left(- 6 {b}^{2}\right) + \left(6 b\right) + \left(- 11\right)$

Remember that + and - together make - so +(-11) = -11

$- 6 {b}^{2} + 6 b - 11$
