factor

12 k^{2} - k - 20

(4 k + 5) (3 k - 4)

Solution steps

12 k^{2} - k - 20

Break the expression into groups

= (12 k^{2} + 15 k) + (- 16 k - 20)

Factor out

3 k

from

12 k^{2} + 15 k : 3 k (4 k + 5)

Factor out

- 4

from

- 16 k - 20 : - 4 (4 k + 5)

= 3 k (4 k + 5) - 4 (4 k + 5)

Factor out common term

4 k + 5

= (4 k + 5) (3 k - 4)

- 2 = ∣ 4 x - 2 ∣

12 x^{2} y - 75 x y^{2}

t - 5 \leq - 7

\frac{3}{5} x = 12

∣ a ∣ < 5
