factor

x^{2} + 21 x + 54

(x + 3) (x + 18)

Solution steps

x^{2} + 21 x + 54

Break the expression into groups

= (x^{2} + 3 x) + (18 x + 54)

Factor out

x

from

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

Factor out

18

from

18 x + 54 : 18 (x + 3)

= x (x + 3) + 18 (x + 3)

Factor out common term

x + 3

= (x + 3) (x + 18)

\frac{3}{x - 2} > 7

\frac{x + 5}{x - 6} < 0

x^{3} + x^{2} \geq 12 x

- \frac{1}{6} + 1

x^{2} + 2 x - 3 \geq 0
