simplify (-x^2-5x-3)-(-7x^2-8x-8)

simplify

(- x^{2} - 5 x - 3) - (- 7 x^{2} - 8 x - 8)

6 x^{2} + 3 x + 5

Solution steps

(- x^{2} - 5 x - 3) - (- 7 x^{2} - 8 x - 8)

Apply rule:

(a) = a

(- x^{2} - 5 x - 3) = - x^{2} - 5 x - 3

= - x^{2} - 5 x - 3 - (- 7 x^{2} - 8 x - 8)

Apply the distributive law:

- (- a - b) = a + b

- (- 7 x^{2} - 8 x - 8) = 7 x^{2} + 8 x + 8

= - x^{2} - 5 x - 3 + 7 x^{2} + 8 x + 8

Group like terms

= - x^{2} + 7 x^{2} - 5 x + 8 x - 3 + 8

Add similar elements:

- x^{2} + 7 x^{2} = 6 x^{2}

= 6 x^{2} - 5 x + 8 x - 3 + 8

Add similar elements:

- 5 x + 8 x = 3 x

= 6 x^{2} + 3 x - 3 + 8

Add the numbers:

- 3 + 8 = 5

= 6 x^{2} + 3 x + 5

2 (x + y + 1)

(- 2 + 8 i) - (- 8 + 10 i)

(- 3 x y^{4})^{3}

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