factor x^4+2x^3-4x^2-8x

factor

x^{4} + 2 x^{3} - 4 x^{2} - 8 x

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

Solution steps

x^{4} + 2 x^{3} - 4 x^{2} - 8 x

Factor out common term

x : x (x^{3} + 2 x^{2} - 4 x - 8)

= x (x^{3} + 2 x^{2} - 4 x - 8)

Factor

x^{3} + 2 x^{2} - 4 x - 8 : (x + 2) (x + 2) (x - 2)

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

Apply exponent rule:

aa = a^{2}

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

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

- 0.7 (- 5 b - 5 b + 7) - 0.9 b

(6^{2})^{8}

- 5 \times 5

\frac{3}{4} 27

2 (\frac{2}{5})^{2}
