factor-x^2-15x-54

factor

- x^{2} - 15 x - 54

- (x + 6) (x + 9)

Solution steps

- x^{2} - 15 x - 54

Break the expression into groups

= (- x^{2} - 6 x) + (- 9 x - 54)

Factor out

- x

from

- x^{2} - 6 x : - x (x + 6)

Factor out

- 9

from

- 9 x - 54 : - 9 (x + 6)

= - x (x + 6) - 9 (x + 6)

Factor out common term

x + 6

= (x + 6) (- x - 9)

Factor

- x - 9 : - (x + 9)

= (x + 6) (- (x + 9))

Apply rule:

a (- b) = - ab

(x + 6) (- (x + 9)) = - (x + 6) (x + 9)

= - (x + 6) (x + 9)

64 x^{6} - 125 y^{6}

\frac{8 - 7 i}{8 + i}

(- 9 + i) (- 9 - i)

3 (x - 1) + 5 = 6 - (x + 2)

(2 x)^{- 1}
