factor x^4+3x^2-4

Solution

factor

x^{4} + 3 x^{2} - 4

Solution

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

Solution steps

x^{4} + 3 x^{2} - 4

Let

u = x^{2}

= u^{2} + 3 u - 4

Factor

u^{2} + 3 u - 4 : (u - 1) (u + 4)

= (u - 1) (u + 4)

Substitute back

u = x^{2}

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

Factor

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

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