[tex]x^{2}[/tex]-4[tex]y^{2}[/tex] = 0
Solution
Here we have to find the factors.
[tex]x^{2} - 4y^{2} = 0[/tex]
Here we can write 4y^2 as (2y)^2
[tex]x^{2} - (2y)^{2} = 0[/tex]
Now we have to use the formula, a^2 - b^2 = (a + b)(a - b)
Here a = x and b = 2y
Therefore, we get
(x + 2y)(x -2y)
Hence, the answer isC. (x + 2y)(x -2y)
