factor x^3-7x^2-15x+105

factor

x^{3} - 7 x^{2} - 15 x + 105

(x - 7) (x^{2} - 15)

Solution steps

x^{3} - 7 x^{2} - 15 x + 105

= (x^{3} - 7 x^{2}) + (- 15 x + 105)

Factor out

x^{2}

from

x^{3} - 7 x^{2} : x^{2} (x - 7)

Factor out

- 15

from

- 15 x + 105 : - 15 (x - 7)

= x^{2} (x - 7) - 15 (x - 7)

Factor out common term

x - 7

= (x - 7) (x^{2} - 15)

x^{5} - 2 x^{- 2}

\frac{15 a b ^{5}}{3 c ^{- 3}}

(n + 1)^{3} - n^{3}

\frac{5}{6} - \frac{7}{30}
