factor 4x^4-5x^2+1

Solution

factor

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

Solution

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

Solution steps

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

Let

u = x^{2}

= 4 u^{2} - 5 u + 1

Factor

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

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

Substitute back

u = x^{2}

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

Factor

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

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

Factor

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

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