factor-x^2-6x-8

factor

- x^{2} - 6 x - 8

- (x + 2) (x + 4)

Solution steps

- x^{2} - 6 x - 8

Break the expression into groups

= (- x^{2} - 2 x) + (- 4 x - 8)

Factor out

- x

from

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

Factor out

- 4

from

- 4 x - 8 : - 4 (x + 2)

= - x (x + 2) - 4 (x + 2)

Factor out common term

x + 2

= (x + 2) (- x - 4)

Factor

- x - 4 : - (x + 4)

= (x + 2) (- (x + 4))

Apply rule:

a (- b) = - ab

(x + 2) (- (x + 4)) = - (x + 2) (x + 4)

= - (x + 2) (x + 4)

(3 x + 9) (x + 1)

(x - \frac{1}{x})^{5}

\frac{1}{4} \times \frac{1}{3}

\frac{y ^{11} \cdot y ^{9}}{y ^{- 3}}

(x + 1) (x - 1)
