factor y^2-8y-20

factor

y^{2} - 8 y - 20

(y + 2) (y - 10)

Solution steps

y^{2} - 8 y - 20

Break the expression into groups

= (y^{2} + 2 y) + (- 10 y - 20)

Factor out

y

from

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

Factor out

- 10

from

- 10 y - 20 : - 10 (y + 2)

= y (y + 2) - 10 (y + 2)

Factor out common term

y + 2

= (y + 2) (y - 10)

- \frac{11 π}{6} + 2 π

72 = 0.045 (\frac{800}{0.2}) (\frac{v ^{2}}{2 \cdot 9.81})

10 - 2 x + 7 \leq 3

12 x + 8 = 44 - 6 x

2 x^{2} - (x - 2) (x + 5) = 7 (x + 3)
