factor

m^{2} - 7 m - 120

(m + 8) (m - 15)

Solution steps

m^{2} - 7 m - 120

Break the expression into groups

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

Factor out

m

from

m^{2} + 8 m : m (m + 8)

Factor out

- 15

from

- 15 m - 120 : - 15 (m + 8)

= m (m + 8) - 15 (m + 8)

= (m + 8) (m - 15)

- 6 x + 3 = 21

y^{- \frac{7}{6}}

27 u^{3} + 125

2 x - 1 \leq 3 x + 4

- 4 (x + 6) = 8
