factor x^2+x-20

factor

x^{2} + x - 20

(x - 4) (x + 5)

Solution steps

x^{2} + x - 20

Break the expression into groups

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

Factor out

x

from

x^{2} - 4 x : x (x - 4)

Factor out

5

from

5 x - 20 : 5 (x - 4)

= x (x - 4) + 5 (x - 4)

Factor out common term

x - 4

= (x - 4) (x + 5)

2 x^{2} = 26

\frac{3}{2} - 5

0 + 4

\frac{7}{25 z ^{3} y} - \frac{1}{35 z ^{2} y}

- \frac{3}{5} (5 k - 10) < - 15
