simplify (-5x^2+7x+2)-(-5x^2-7x+2)

simplify

(- 5 x^{2} + 7 x + 2) - (- 5 x^{2} - 7 x + 2)

14 x

Solution steps

(- 5 x^{2} + 7 x + 2) - (- 5 x^{2} - 7 x + 2)

Apply rule:

(a) = a

(- 5 x^{2} + 7 x + 2) = - 5 x^{2} + 7 x + 2

= - 5 x^{2} + 7 x + 2 - (- 5 x^{2} - 7 x + 2)

Apply the distributive law:

- (- a - b) = a + b

- (- 5 x^{2} - 7 x + 2) = 5 x^{2} + 7 x - 2

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

Group like terms

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

Add similar elements:

- 5 x^{2} + 5 x^{2} = 0

= 7 x + 7 x + 2 - 2

Add similar elements:

7 x + 7 x = 14 x

= 14 x + 2 - 2

Subtract the numbers:

2 - 2 = 0

= 14 x

(- 6 + 6 i) (- 1 + 5 i)

(x + y)^{2} - (2 x - y)^{2}

2 a x - 4 b x + 2 a y - 4 b y

- 58

(5 - 2 i) + (3 + 3 i)
