factor x^2-4x-12

factor

x^{2} - 4 x - 12

(x + 2) (x - 6)

Solution steps

x^{2} - 4 x - 12

Break the expression into groups

= (x^{2} + 2 x) + (- 6 x - 12)

Factor out

x

from

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

Factor out

- 6

from

- 6 x - 12 : - 6 (x + 2)

= x (x + 2) - 6 (x + 2)

Factor out common term

x + 2

= (x + 2) (x - 6)

- 6 < 6 - 2 x \leq 10

216 x^{4} a y - 6 y^{5} a

5 (4 x - 8) = - 180

(\frac{2 x ^{3}}{x ^{3} \cdot 2 x ^{2} \cdot 2 x ^{4}})^{4}

4 x < - 12
