Find and simplify the product of the following rational expression

alekssr [168]

I would say it’s b

You can cross cancel (x-3) out of both fractions
Then you have x+2/ x times 3/4
Multiply the numerators
3(x+2)
And the denominators
x • 4 = 4x
Leaving you with 3(x+2)/4x
You can simplify it further into 3x+ 6/ 4x which is option b, though it is technically simplified with the parentheses.
