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

Solution

factor

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

Solution

(2 y + 1) (2 y - 1) (y + 1) (y - 1)

Solution steps

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

Let

u = y^{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 = y^{2}

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

Factor

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

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

Factor

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

= (2 y + 1) (2 y - 1) (y + 1) (y - 1)
