factor 5x^4-15x^2-20

factor

5 x^{4} - 15 x^{2} - 20

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

Solution steps

5 x^{4} - 15 x^{2} - 20

Factor out common term

5 : 5 (x^{4} - 3 x^{2} - 4)

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

Factor

x^{4} - 3 x^{2} - 4 : (x^{2} + 1) (x + 2) (x - 2)

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

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

e^{\frac{π}{3} i}

(s + 1) (2 s + 1)

\frac{2}{5} x^{\frac{5}{2}}

3 \frac{3}{4} + 5 \frac{5}{9} + 7 \frac{1}{12}
