factor x^3-7x^2-4x+28

factor

x^{3} - 7 x^{2} - 4 x + 28

(x - 7) (x + 2) (x - 2)

Solution steps

x^{3} - 7 x^{2} - 4 x + 28

= (x^{3} - 7 x^{2}) + (- 4 x + 28)

Factor out

x^{2}

from

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

Factor out

- 4

from

- 4 x + 28 : - 4 (x - 7)

= x^{2} (x - 7) - 4 (x - 7)

Factor out common term

x - 7

= (x - 7) (x^{2} - 4)

Factor

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

= (x - 7) (x + 2) (x - 2)

\frac{- \frac{15}{17}}{\frac{8}{17}}

- 22 > - 10 + b

27 \cdot 3

x^{5} + 4 x^{4} - 21 x^{3} + 2 x + 14

4 (3 - 5 x) + 1 = - 4 x - 8 - 16 x
