factor 5x^4-9x^2+4

Solution

factor

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

Solution

(5 x^{2} - 4) (x + 1) (x - 1)

Solution steps

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

Let

u = x^{2}

= 5 u^{2} - 9 u + 4

Factor

5 u^{2} - 9 u + 4 : (5 u - 4) (u - 1)

= (5 u - 4) (u - 1)

Substitute back

u = x^{2}

= (5 x^{2} - 4) (x^{2} - 1)

Factor

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

= (5 x^{2} - 4) (x + 1) (x - 1)
