factor x^3+8x^2-9x-72

factor

x^{3} + 8 x^{2} - 9 x - 72

(x + 8) (x + 3) (x - 3)

Solution steps

x^{3} + 8 x^{2} - 9 x - 72

= (x^{3} + 8 x^{2}) + (- 9 x - 72)

Factor out

x^{2}

from

x^{3} + 8 x^{2} : x^{2} (x + 8)

Factor out

- 9

from

- 9 x - 72 : - 9 (x + 8)

= x^{2} (x + 8) - 9 (x + 8)

Factor out common term

x + 8

= (x + 8) (x^{2} - 9)

Factor

x^{2} - 9 : (x + 3) (x - 3)

= (x + 8) (x + 3) (x - 3)

10 x - 6 = - 3

12 x^{2} - x y - y^{2}

6020 - x (280 - 273) = 0

a^{2} + 11 ab + 18 b^{2}

\frac{( 3 m n ^{2} )}{5 m n ^{2}} (\frac{8 m n ^{3}}{2 mn})^{2}
