factor 3y^2+11y-20

factor

3 y^{2} + 11 y - 20

(3 y - 4) (y + 5)

Solution steps

3 y^{2} + 11 y - 20

Break the expression into groups

= (3 y^{2} - 4 y) + (15 y - 20)

Factor out

y

from

3 y^{2} - 4 y : y (3 y - 4)

Factor out

5

from

15 y - 20 : 5 (3 y - 4)

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

Factor out common term

3 y - 4

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

12 x^{2} + 8 x - 15 = 0

∣ 2 y - 3 ∣ \geq 12

0 = x^{2} - 8 x + 13

2 x + 24 = \frac{2}{7} x

6 x^{2} + 3 x = 0
