factor x^4-5x^2-36

Solution

factor

x^{4} - 5 x^{2} - 36

Solution

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

Solution steps

x^{4} - 5 x^{2} - 36

Let

u = x^{2}

= u^{2} - 5 u - 36

Factor

u^{2} - 5 u - 36 : (u + 4) (u - 9)

= (u + 4) (u - 9)

Substitute back

u = x^{2}

= (x^{2} + 4) (x^{2} - 9)

Factor

x^{2} - 9 : (x + 3) (x - 3)

= (x^{2} + 4) (x + 3) (x - 3)
