(- 4 x^{2} + 2) - (- 7 x^{2} + 10 x + 1)

3 x^{2} - 10 x + 1

Solution steps

(- 4 x^{2} + 2) - (- 7 x^{2} + 10 x + 1)

Apply rule:

(a) = a

(- 4 x^{2} + 2) = - 4 x^{2} + 2

= - 4 x^{2} + 2 - (- 7 x^{2} + 10 x + 1)

Apply the distributive law:

- (- a + b) = a - b

- (- 7 x^{2} + 10 x + 1) = 7 x^{2} - 10 x - 1

= - 4 x^{2} + 2 + 7 x^{2} - 10 x - 1
