factor x^4-13x^2+36

Solution

factor

x^{4} - 13 x^{2} + 36

Solution

(x + 2) (x - 2) (x + 3) (x - 3)

Solution steps

x^{4} - 13 x^{2} + 36

Let

u = x^{2}

= u^{2} - 13 u + 36

Factor

u^{2} - 13 u + 36 : (u - 4) (u - 9)

= (u - 4) (u - 9)

Substitute back

u = x^{2}

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

Factor

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

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

Factor

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

= (x + 2) (x - 2) (x + 3) (x - 3)
