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

factor

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

(x + 5) (x + 2) (x - 2)

Solution steps

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

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

Factor out

x^{2}

from

x^{3} + 5 x^{2} : x^{2} (x + 5)

Factor out

- 4

from

- 4 x - 20 : - 4 (x + 5)

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

Factor out common term

x + 5

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

Factor

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

= (x + 5) (x + 2) (x - 2)

a^{2} b^{3} - 4 b^{6} - 6 a^{2} + 24 b^{3}

(12 + 6) (- 8 - 2)

35000 \cdot (1 + 0.1)^{20}

2 x + \frac{4}{5} \leq 1

x^{2} = 3 x - 12
