factor x^4-6x^2+8

Solution

factor

x^{4} - 6 x^{2} + 8

Solution

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

Solution steps

x^{4} - 6 x^{2} + 8

Let

u = x^{2}

= u^{2} - 6 u + 8

Factor

u^{2} - 6 u + 8 : (u - 2) (u - 4)

= (u - 2) (u - 4)

Substitute back

u = x^{2}

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

Factor

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

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