factor x^3-9x^2+9x-81

factor

x^{3} - 9 x^{2} + 9 x - 81

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

Solution steps

x^{3} - 9 x^{2} + 9 x - 81

= (x^{3} - 9 x^{2}) + (9 x - 81)

Factor out

x^{2}

from

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

Factor out

9

from

9 x - 81 : 9 (x - 9)

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

Factor out common term

x - 9

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

\frac{( 2 a ^{- 2} b ) ^{- 3}}{5 a ^{2} b ^{4}}

(- 4 y^{4})^{2}

\frac{2}{5} x - 5 \geq 3

4 (x^{2} - 6) + 8 = - 4

- u^{2} + 7 u - 12
