PLS HELP NEED ASAP
need help solving this equation idek what this means

Answer 1

`(x+4)/(3(x-1))`

Question

`x^2/x-1/3x^2/x+4`

This can be written as a/b * d/c using the KCF method, which stands for keep, change, flip when dividing fractions. You keep the first fraction, change the sign from divide to multiply, and flip the last fraction.

For example:

4/5 / 6/7 =

4/5 * 7/6

28/30

14/15

`(x^2)/(x-1) * (x+4)/(3x^2)`

Next, multiply top and bottom to combine the fractions.

`(x^3+4x^2)/(3x^3-3x^2)`

Factor
`x^2` out of
`x^3 + 4x^2`.

`(x^2(x+4))/(3x^3-3x^2)`

Factor
`3x^2` out of
`3x^3-3x^2`.

`(x^2(x+4))/(3x^2(x-1))`

Cancel out
`x^2` from top and bottom.

`(x+4)/(3(x-1))`
