x^{2} - 16 x - 36

(x + 2) (x - 18)

Solution steps

x^{2} - 16 x - 36

Break the expression into groups

= (x^{2} + 2 x) + (- 18 x - 36)

x

from

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

Factor out

- 18

from

- 18 x - 36 : - 18 (x + 2)

= x (x + 2) - 18 (x + 2)

x + 2

= (x + 2) (x - 18)

x (x + 10) \geq 24

16 x - 8 + 2 x = 100

x^{2} y^{2} - 49

x^{27} < 16
