factor

x^{2} + 7 x - 120

(x - 8) (x + 15)

Solution steps

x^{2} + 7 x - 120

Break the expression into groups

= (x^{2} - 8 x) + (15 x - 120)

Factor out

x

from

x^{2} - 8 x : x (x - 8)

Factor out

15

from

15 x - 120 : 15 (x - 8)

= x (x - 8) + 15 (x - 8)

Factor out common term

x - 8

= (x - 8) (x + 15)

3 x^{2} - 2 x < 2 x^{2} + 35

5 = \frac{5 - 2 b}{4} (2)^{2} + b^{2}

2 x^{2} - 4 x - 30 = 0

\frac{2 + 3 3}{3 + 5}

y^{2} - 2 y - 2 = 0
