factor x^2+12x+27

factor

x^{2} + 12 x + 27

(x + 3) (x + 9)

Solution steps

x^{2} + 12 x + 27

Break the expression into groups

= (x^{2} + 3 x) + (9 x + 27)

Factor out

x

from

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

Factor out

9

from

9 x + 27 : 9 (x + 3)

= x (x + 3) + 9 (x + 3)

Factor out common term

x + 3

= (x + 3) (x + 9)

3 x - 5 > - 4 x + 9

k^{2} - 3 k = 0

x + (x + 2) = 20 + (x + 4)

(x - 1) (x - 7) \leq 0

5 z^{2} + 4 z - 1 = 0
