Question

The least common denominator that can be used to add and is 24x2. What value of b is needed to rewrite the first fraction with the LCD?

Answer 1

3 is the answer to the question.

Answer 2

`(x+1)/(8x^2)` and
`(2x-3)/(12x)`

LCD is 24x^2

we need to find out b when multiply with first fraction to get 3x+3/24x^2

`(x+1)/(8x^2) ((b)/(b)) =(3x+3)/(24x^2)`

We need to find out a number what multiply with 8x^2 to get 24x^2

`8x^2 * 3 = 24x^2`

`(x+1)/(8x^2) ((3)/(3)) =(3(x+1))/(24x^2)=(3x+3)/(24x^2)`

So the value of b is 3
