factor

3 r^{2} + 5 r - 2

(3 r - 1) (r + 2)

Solution steps

3 r^{2} + 5 r - 2

Break the expression into groups

= (3 r^{2} - r) + (6 r - 2)

Factor out

r

from

3 r^{2} - r : r (3 r - 1)

Factor out

2

from

6 r - 2 : 2 (3 r - 1)

= r (3 r - 1) + 2 (3 r - 1)

Factor out common term

3 r - 1

= (3 r - 1) (r + 2)

6 x^{2} + 13 x + 5

\frac{x ^{2}}{4} < 1

∣ a ∣ = 3

\frac{x - 1}{x + 5} \leq 0

\frac{10}{6} \cdot \frac{6}{15}
