simplify

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

7 x^{2} + 5 x - 9

Solution steps

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

Apply rule:

(a) = a

(9 x + 1) = 9 x + 1

= 9 x + 1 - (- 7 x^{2} + 4 x + 10)

Apply the distributive law:

- (- a + b) = a - b

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

= 9 x + 1 + 7 x^{2} - 4 x - 10

Group like terms

= 7 x^{2} + 9 x - 4 x + 1 - 10

Add similar elements:
