factor s^2-2s-3

factor

s^{2} - 2 s - 3

(s + 1) (s - 3)

Solution steps

s^{2} - 2 s - 3

Break the expression into groups

= (s^{2} + s) + (- 3 s - 3)

Factor out

s

from

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

Factor out

- 3

from

- 3 s - 3 : - 3 (s + 1)

= s (s + 1) - 3 (s + 1)

Factor out common term

s + 1

= (s + 1) (s - 3)

\frac{4}{x - 6} > \frac{2}{x + 4}

∣ x + 5 ∣ = 3

x^{7}

x^{2} - x \geq 2

\frac{x + 3}{x + 1} \geq 0
