factor x^2-18x-19

factor

x^{2} - 18 x - 19

(x + 1) (x - 19)

Solution steps

x^{2} - 18 x - 19

Break the expression into groups

= (x^{2} + x) + (- 19 x - 19)

Factor out

x

from

x^{2} + x : x (x + 1)

Factor out

- 19

from

- 19 x - 19 : - 19 (x + 1)

= x (x + 1) - 19 (x + 1)

Factor out common term

x + 1

= (x + 1) (x - 19)

x^{2} - 4 x = 45

2 (1 - x) + 7 \leq 4 (2 x - 1)

(x - 7) (4 - x) (x + 1) < 0

9 h - 2 \leq 10 h - 5

\frac{4 x}{3} + 1 = - 2
