factor 5x^4-10x^2-315

factor

5 x^{4} - 10 x^{2} - 315

5 (x^{2} + 7) (x + 3) (x - 3)

Solution steps

5 x^{4} - 10 x^{2} - 315

Factor out common term

5 : 5 (x^{4} - 2 x^{2} - 63)

= 5 (x^{4} - 2 x^{2} - 63)

Factor

x^{4} - 2 x^{2} - 63 : (x^{2} + 7) (x + 3) (x - 3)

= 5 (x^{2} + 7) (x + 3) (x - 3)

\frac{2}{5} \times \frac{3}{2}

- 16 x - 9

(s + 1)^{3} (s + 3)
