3 r^{2} - 16 r - 12

(3 r + 2) (r - 6)

Solution steps

3 r^{2} - 16 r - 12

Break the expression into groups

= (3 r^{2} + 2 r) + (- 18 r - 12)

Factor out

r

from

3 r^{2} + 2 r : r (3 r + 2)

Factor out

- 6

from

- 18 r - 12 : - 6 (3 r + 2)

= r (3 r + 2) - 6 (3 r + 2)

3 r + 2

= (3 r + 2) (r - 6)

x^{2} + 3 x \geq 10

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

x - 1 = 6

\frac{3}{8} + \frac{5}{12}

2 (4 a - 12) + 3 a = 6 a + 1
