factor x^2+2x-63

factor

x^{2} + 2 x - 63

(x - 7) (x + 9)

Solution steps

x^{2} + 2 x - 63

Break the expression into groups

= (x^{2} - 7 x) + (9 x - 63)

Factor out

x

from

x^{2} - 7 x : x (x - 7)

Factor out

9

from

9 x - 63 : 9 (x - 7)

= x (x - 7) + 9 (x - 7)

Factor out common term

x - 7

= (x - 7) (x + 9)

\frac{7}{9} - \frac{2}{9}

\frac{10 - 5}{5 + 2}

- 5 (5 z - 6) < - 30 z + 10

8 x^{2} + 16 x = 24

(x + 4) (x^{2} - 5 x - 14) \geq 0
