simplify (-4x^2-2x-6)-(-7x^2-2x-2)

simplify

(- 4 x^{2} - 2 x - 6) - (- 7 x^{2} - 2 x - 2)

3 x^{2} - 4

Solution steps

(- 4 x^{2} - 2 x - 6) - (- 7 x^{2} - 2 x - 2)

Apply rule:

(a) = a

(- 4 x^{2} - 2 x - 6) = - 4 x^{2} - 2 x - 6

= - 4 x^{2} - 2 x - 6 - (- 7 x^{2} - 2 x - 2)

Apply the distributive law:

- (- a - b) = a + b

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

= - 4 x^{2} - 2 x - 6 + 7 x^{2} + 2 x + 2

Group like terms

= - 4 x^{2} + 7 x^{2} - 2 x + 2 x - 6 + 2

Add similar elements:

- 4 x^{2} + 7 x^{2} = 3 x^{2}

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

Add similar elements:

- 2 x + 2 x = 0

= 3 x^{2} - 6 + 2

Add the numbers:

- 6 + 2 = - 4

= 3 x^{2} - 4
