factor

x^{2} - 12 x - 13

(x + 1) (x - 13)

Solution steps

x^{2} - 12 x - 13

Break the expression into groups

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

Factor out

x

from

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

Factor out

- 13

from

- 13 x - 13 : - 13 (x + 1)

= x (x + 1) - 13 (x + 1)

Factor out common term

x + 1

= (x + 1) (x - 13)

3 x^{2} - 9 x + 6 = 0

∣ x - 5 ∣ \leq 2 x

∣ 3 x - 1 ∣ - 3 \leq \frac{x}{2} + 1

e^{1} - e^{0}

1 + (a - 3 b)^{3}
