factor x^4-10x^2+9

Solution

factor

x^{4} - 10 x^{2} + 9

Solution

(x + 1) (x - 1) (x + 3) (x - 3)

Solution steps

x^{4} - 10 x^{2} + 9

Let

u = x^{2}

= u^{2} - 10 u + 9

Factor

u^{2} - 10 u + 9 : (u - 1) (u - 9)

= (u - 1) (u - 9)

Substitute back

u = x^{2}

= (x^{2} - 1) (x^{2} - 9)

Factor

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

= (x + 1) (x - 1) (x^{2} - 9)

Factor

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

= (x + 1) (x - 1) (x + 3) (x - 3)
