How do you simplify this equation?
faust18 [17]

<u>Answer:</u>

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

<u>How I got that:</u>

<u />

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!
