factor y^2-y-20

factor

y^{2} - y - 20

(y + 4) (y - 5)

Solution steps

y^{2} - y - 20

Break the expression into groups

= (y^{2} + 4 y) + (- 5 y - 20)

Factor out

y

from

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

Factor out

- 5

from

- 5 y - 20 : - 5 (y + 4)

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

Factor out common term

y + 4

= (y + 4) (y - 5)

\frac{( - 1 ) ^{1} 0. 5 ^{2 + 4}}{1 ! ( 2 + 4 )}

7 x^{2} - 112

(\frac{a}{b})^{- 10}

\frac{x + 2}{x - 1} \leq 0
