- 14 x

Solution steps

(- 5 x^{2} - 7 x + 2) - (- 5 x^{2} + 7 x + 2)

Apply rule:

(a) = a

(- 5 x^{2} - 7 x + 2) = - 5 x^{2} - 7 x + 2

= - 5 x^{2} - 7 x + 2 - (- 5 x^{2} + 7 x + 2)

Apply the distributive law:

- (- a + b) = a - b

- (- 5 x^{2} + 7 x + 2) = 5 x^{2} - 7 x - 2

= - 5 x^{2} - 7 x + 2 + 5 x^{2} - 7 x - 2
