simplify (-10x^2+2x-10)-(-10x^2+3)

simplify

(- 10 x^{2} + 2 x - 10) - (- 10 x^{2} + 3)

2 x - 13

Solution steps

(- 10 x^{2} + 2 x - 10) - (- 10 x^{2} + 3)

Apply rule:

(a) = a

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

= - 10 x^{2} + 2 x - 10 - (- 10 x^{2} + 3)

Apply the distributive law:

- (- a + b) = a - b

- (- 10 x^{2} + 3) = 10 x^{2} - 3

= - 10 x^{2} + 2 x - 10 + 10 x^{2} - 3

Group like terms

= - 10 x^{2} + 10 x^{2} + 2 x - 10 - 3

Add similar elements:

- 10 x^{2} + 10 x^{2} = 0

= 2 x - 10 - 3

Subtract the numbers:

- 10 - 3 = - 13

= 2 x - 13
