simplify (-4x^2+3x-5)-(-7x-9)

simplify

(- 4 x^{2} + 3 x - 5) - (- 7 x - 9)

- 4 x^{2} + 10 x + 4

Solution steps

(- 4 x^{2} + 3 x - 5) - (- 7 x - 9)

Apply rule:

(a) = a

(- 4 x^{2} + 3 x - 5) = - 4 x^{2} + 3 x - 5

= - 4 x^{2} + 3 x - 5 - (- 7 x - 9)

Apply the distributive law:

- (- a - b) = a + b

- (- 7 x - 9) = 7 x + 9

= - 4 x^{2} + 3 x - 5 + 7 x + 9

Group like terms

= - 4 x^{2} + 3 x + 7 x - 5 + 9

Add similar elements:

3 x + 7 x = 10 x

= - 4 x^{2} + 10 x - 5 + 9

Add the numbers:

- 5 + 9 = 4

= - 4 x^{2} + 10 x + 4

- 6 (2 + x)

\frac{- 6}{- 1}

\frac{3 ( w ^{5} ) ^{2}}{12 w ^{9}}

(2 x^{3} + 4 x^{2} - 5) - (4 x^{3} - x^{2} + 3 x + 12)

(2 x^{4}) (3 x^{6}) (- 2 x)
