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

simplify

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

8 x^{2}

Solution steps

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

Apply rule:

(a) = a

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

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

Apply the distributive law:

- (- a - b) = a + b

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

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

Group like terms

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

Add similar elements:

- 2 x^{2} + 10 x^{2} = 8 x^{2}

= 8 x^{2} - 10 x + 10 x

Add similar elements:

- 10 x + 10 x = 0

= 8 x^{2}

(x - 2) (x + 2) (x - 2)
