factor 9x^4-13x^2+4

Solution

factor

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

Solution

(3 x + 2) (3 x - 2) (x + 1) (x - 1)

Solution steps

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

Let

u = x^{2}

= 9 u^{2} - 13 u + 4

Factor

9 u^{2} - 13 u + 4 : (9 u - 4) (u - 1)

= (9 u - 4) (u - 1)

Substitute back

u = x^{2}

= (9 x^{2} - 4) (x^{2} - 1)

Factor

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

= (3 x + 2) (3 x - 2) (x^{2} - 1)

Factor

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

= (3 x + 2) (3 x - 2) (x + 1) (x - 1)
