factor 21y^2+10y-16

factor

21 y^{2} + 10 y - 16

(3 y - 2) (7 y + 8)

Solution steps

21 y^{2} + 10 y - 16

Break the expression into groups

= (21 y^{2} - 14 y) + (24 y - 16)

Factor out

7 y

from

21 y^{2} - 14 y : 7 y (3 y - 2)

Factor out

8

from

24 y - 16 : 8 (3 y - 2)

= 7 y (3 y - 2) + 8 (3 y - 2)

Factor out common term

3 y - 2

= (3 y - 2) (7 y + 8)

t^{2} + 20 t - 4 = 0

0 = - 16 t^{2} + 96 t

7 - 2 x \geq 15

25 \cdot 5

- 3 x^{2} + 4 x = 0
