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

factor

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

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

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)

(\frac{6}{10})^{2}

(\frac{x}{3})^{3} (9 x)^{- 2}

(\frac{8}{3})^{2}

56 - 27 b - 18 b^{2}

- 4 x^{2} + 16 x = 23
