Factorise x^2-y^2/100

Mathematics
1 answer:
Ivanshal [37]3 years ago
4 0
The equation is the following
x^2- \frac{y^2}{100}

This is a difference of two squares, the first one being the square of x, the second one being the square of \frac{y}{10}. The difference of two squares can be factorized as
A^2 - B^2 = (A+B)(A-B)

If we apply this rule to our equation, we find
x^2- \frac{y^2}{100}=(x+ \frac{y}{10})(x- \frac{y}{10})
