factor x^3+4x^2+5x+20

factor

x^{3} + 4 x^{2} + 5 x + 20

(x + 4) (x^{2} + 5)

Solution steps

x^{3} + 4 x^{2} + 5 x + 20

= (x^{3} + 4 x^{2}) + (5 x + 20)

Factor out

x^{2}

from

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

Factor out

5

from

5 x + 20 : 5 (x + 4)

= x^{2} (x + 4) + 5 (x + 4)

Factor out common term

x + 4

= (x + 4) (x^{2} + 5)

- \frac{7}{- 2}

3 x^{2} - 2 x + 1 = 0

21 k^{2} + 4 k - 1

x^{2} + \frac{1}{6} x - \frac{1}{6} = 0

(8 x^{6})^{- \frac{2}{3}}
