factor x^8+x^4-240

Solution

factor

x^{8} + x^{4} - 240

Solution

(x^{4} - 15) (x^{4} + 16)

Solution steps

x^{8} + x^{4} - 240

Let

u = x^{2}

= u^{4} + u^{2} - 240

Factor

u^{4} + u^{2} - 240 : (u^{2} - 15) (u^{2} + 16)

= (u^{2} - 15) (u^{2} + 16)

Substitute back

u = x^{2}

= (x^{4} - 15) (x^{4} + 16)
