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

simplify

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

- 4 x^{2} - 2 x - 14

Solution steps

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

Apply rule:

(a) = a

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

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

Apply the distributive law:

- (a + b) = - a - b

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

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

Group like terms

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

Add similar elements:

- 2 x^{2} - 2 x^{2} = - 4 x^{2}

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

Subtract the numbers:

- 7 - 7 = - 14

= - 4 x^{2} - 2 x - 14
