Question

How do you simplify this equation?

Answer 1

Answer:

The answer is B --> $\frac{x^{2} }{3x^{2} -1}$

How I got that:

These are really easy, you're simply looking for numbers that you can factor down. Like here:

I took:

$\frac{4x^{2} }{12x^{2} -4}$

and saw that I could factor out 4 from the denominator:

$\frac{4x^{2} }{4(3x^{2} -1)}$

and then I canceled out the common factor (4 because its on both sides):

$\frac{x^{2} }{3x^{2} -1}$

And there ya go!
