r^{2} - 2 r - 24

(r + 4) (r - 6)

Solution steps

r^{2} - 2 r - 24

Break the expression into groups

= (r^{2} + 4 r) + (- 6 r - 24)

Factor out

r

from

r^{2} + 4 r : r (r + 4)

Factor out

- 6

from

- 6 r - 24 : - 6 (r + 4)

= r (r + 4) - 6 (r + 4)

Factor out common term

r + 4

= (r + 4) (r - 6)

(- 3 x)^{- 3}

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

5 - 4 a \leq 9

\frac{11}{12} - \frac{1}{6}

- 2 x + 8 = - 10
