factor y^2-4x^2

Solution

factor

y^{2} - 4 x^{2}

Solution

(y + 2 x) (y - 2 x)

Solution steps

y^{2} - 4 x^{2}

Simplify

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