factor

x^{2} - 2 x - 143

(x + 11) (x - 13)

Solution steps

x^{2} - 2 x - 143

Break the expression into groups

= (x^{2} + 11 x) + (- 13 x - 143)

Factor out

x

from

x^{2} + 11 x : x (x + 11)

Factor out

- 13

from

- 13 x - 143 : - 13 (x + 11)

= x (x + 11) - 13 (x + 11)

x + 11

= (x + 11) (x - 13)

\frac{( 1.05 - 0.95 ) ^{2}}{12}

3 x - 4 \leq 8

\frac{3}{4} (- 6)

x^{2} + 2 x + 4 < 0

1000 + (b - 8)^{3}
