factor y^4-x^2

Solution

factor

y^{4} - x^{2}

Solution

(y^{2} + x) (y^{2} - x)

Solution steps

y^{4} - x^{2}

Simplify

y^{4} : (y^{2})^{2}

= (y^{2})^{2} - x^{2}

Apply Difference of Two Squares Formula:

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

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

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