factor x^4+x^2-20

Solution

factor

x^{4} + x^{2} - 20

Solution

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

Solution steps

x^{4} + x^{2} - 20

Let

u = x^{2}

= u^{2} + u - 20

Factor

u^{2} + u - 20 : (u - 4) (u + 5)

= (u - 4) (u + 5)

Substitute back

u = x^{2}

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

Factor

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

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