factor x^4-14x^2-32

Solution

factor

x^{4} - 14 x^{2} - 32

Solution

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

Solution steps

x^{4} - 14 x^{2} - 32

Let

u = x^{2}

= u^{2} - 14 u - 32

Factor

u^{2} - 14 u - 32 : (u + 2) (u - 16)

= (u + 2) (u - 16)

Substitute back

u = x^{2}

= (x^{2} + 2) (x^{2} - 16)

Factor

x^{2} - 16 : (x + 4) (x - 4)

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