factor-x^2-9x-18

factor

- x^{2} - 9 x - 18

- (x + 3) (x + 6)

Solution steps

- x^{2} - 9 x - 18

Break the expression into groups

= (- x^{2} - 3 x) + (- 6 x - 18)

Factor out

- x

from

- x^{2} - 3 x : - x (x + 3)

Factor out

- 6

from

- 6 x - 18 : - 6 (x + 3)

= - x (x + 3) - 6 (x + 3)

Factor out common term

x + 3

= (x + 3) (- x - 6)

Factor

- x - 6 : - (x + 6)

= (x + 3) (- (x + 6))

Apply rule:

a (- b) = - ab

(x + 3) (- (x + 6)) = - (x + 3) (x + 6)

= - (x + 3) (x + 6)

\frac{x ^{3} y ^{- 2}}{z ^{2}}

\frac{5}{2 \frac{3}{5}}

3 x^{2} + 3 x - 4 x y - 4 y

6 x^{2} - 30 x + 24

4 \geq s - \frac{2}{3}
