factor 10y^2-21y-10

factor

10 y^{2} - 21 y - 10

(5 y + 2) (2 y - 5)

Solution steps

10 y^{2} - 21 y - 10

Break the expression into groups

= (10 y^{2} + 4 y) + (- 25 y - 10)

Factor out

2 y

from

10 y^{2} + 4 y : 2 y (5 y + 2)

Factor out

- 5

from

- 25 y - 10 : - 5 (5 y + 2)

= 2 y (5 y + 2) - 5 (5 y + 2)

Factor out common term

5 y + 2

= (5 y + 2) (2 y - 5)

9 x - 10 = 5 x + 2 (2 x - 5)

\frac{6}{7} x = - 18

- 2 (7 - n) + 4

\frac{x + 2}{∣ x ∣ - 4} \geq - 1

x^{2} + 7 x - 30
