factor x^4-24x^2-25

Solution

factor

x^{4} - 24 x^{2} - 25

Solution

(x^{2} + 1) (x + 5) (x - 5)

Solution steps

x^{4} - 24 x^{2} - 25

Let

u = x^{2}

= u^{2} - 24 u - 25

Factor

u^{2} - 24 u - 25 : (u + 1) (u - 25)

= (u + 1) (u - 25)

Substitute back

u = x^{2}

= (x^{2} + 1) (x^{2} - 25)

Factor

x^{2} - 25 : (x + 5) (x - 5)

= (x^{2} + 1) (x + 5) (x - 5)
