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)

(5 x^{2} + 8 x) + (x^{2} - 5 x + 1)

(- 1 - 3 i) (- 8 - 6 i)

4 (3 a^{4})^{2}

\frac{35}{12}

(r cos (θ))^{2} + (r sin (θ))^{2}
