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)

16 - (x - y)^{2}

\frac{x - 2}{x + 1} \leq 0

x^{2} - 144

(x + 9)^{2} + 15 (x + 9) + 56 = 0

0 + \frac{1}{2}
