Question

Solve the rational expression 9x+3/12x+4

Answer 1

The answer is

`(3)/(4)`

Explanation:

`(9x + 3)/(12x + 4)`

To solve the rational expression factorize both the numerator and the denominator.

For the numerator

9x + 3

Factorize 3 out

We have

3( 3x + 1)

For the denominator

12x + 4

Factorize 4 out

That's

4( 3x + 1)

So we now have

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

Reduce the expression with (3x + 1)

We have the final answer as

`(3)/(4)`
