Problem:
x+2 x3
_________  _________
2x^2+5x+2 2x^25x3
*Simplify the expression
2x^2+5x+2 =(x+2)(2x+1)
2x^25x3 =(2x+1)(x3)
So x+2/(x+2)(2x+1) = 1/2x+1
x3/(2x+1)(x3) = 1/2x+1
Finally 1/2x+1  1/2x+1 = 0
Let's take a look at the problem:
(x+2)/(2x^2+5x+2)  (x3)/(2x^25x3)
Let's try to factor the denominators first:
2x^2+5x+2 factors are (2x+1)(x+2)
2x^25x3 factors are (2x+1)(x3)
Now, let's rewrite the problem:
(x+2)/(2x+1)(x+2)  (x3)/(2x+1)x3)
Reduce each fraction, then you will have the same denominator for both fractions. Once you do those steps, you should easily see what the answer will be.
I hope this helps.
