factor x^2+x-12

factor

x^{2} + x - 12

(x - 3) (x + 4)

Solution steps

x^{2} + x - 12

Break the expression into groups

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

Factor out

x

from

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

Factor out

4

from

4 x - 12 : 4 (x - 3)

= x (x - 3) + 4 (x - 3)

Factor out common term

x - 3

= (x - 3) (x + 4)

x^{4} - 256 \geq 0

\frac{1}{4} + 2

2 x^{2} + 8 x - 32

x^{2} - 4 = 0

\frac{15}{48} \div (\frac{3}{8} - \frac{7}{12})
