simplify (-3x^2-3x-7)-(x^2+8x)

simplify

(- 3 x^{2} - 3 x - 7) - (x^{2} + 8 x)

- 4 x^{2} - 11 x - 7

Solution steps

(- 3 x^{2} - 3 x - 7) - (x^{2} + 8 x)

Apply rule:

(a) = a

(- 3 x^{2} - 3 x - 7) = - 3 x^{2} - 3 x - 7

= - 3 x^{2} - 3 x - 7 - (x^{2} + 8 x)

Apply the distributive law:

- (a + b) = - a - b

- (x^{2} + 8 x) = - x^{2} - 8 x

= - 3 x^{2} - 3 x - 7 - x^{2} - 8 x
