factor-2y^2-9y-10

factor

- 2 y^{2} - 9 y - 10

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

Solution steps

- 2 y^{2} - 9 y - 10

Break the expression into groups

= (- 2 y^{2} - 4 y) + (- 5 y - 10)

Factor out

- 2 y

from

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

Factor out

- 5

from

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

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

Factor out common term

y + 2

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

Factor

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

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

Apply rule:

a (- b) = - ab

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

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

2 x^{2} - 5 x = 12

1 \leq \frac{b}{2} - 1

\frac{4}{3} π 7^{3}

6 x^{2} + 6 x - 1 = 0

\frac{∣ x + 1 ∣}{x - 1} \leq 2
