factor x^8+x^4-2

Solution

factor

x^{8} + x^{4} - 2

Solution

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

Solution steps

x^{8} + x^{4} - 2

Let

u = x^{2}

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

Factor

u^{4} + u^{2} - 2 : (u + 1) (u - 1) (u^{2} + 2)

= (u + 1) (u - 1) (u^{2} + 2)

Substitute back

u = x^{2}

= (x^{2} + 1) (x^{2} - 1) (x^{4} + 2)

Factor

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

= (x^{2} + 1) (x + 1) (x - 1) (x^{4} + 2)
