s^{2} + 3 s - 40

(s - 5) (s + 8)

Break the expression into groups

= (s^{2} - 5 s) + (8 s - 40)

Factor out

s

from

s^{2} - 5 s : s (s - 5)

Factor out

8

from

8 s - 40 : 8 (s - 5)

= s (s - 5) + 8 (s - 5)

Factor out common term

s - 5

= (s - 5) (s + 8)

32 + 4

- 12 \leq t + 7

5 ∣ x ∣ + 6 \geq 1

x^{2} - 10 x + 8 = 0

(a - b + 1)^{2} - (1 - a - b)^{2}
