id start by factoring. what can you pull out of both the numerator and the denominator.

yep, you can also cancel something as well.

the most important thing about canceling is that the term u are canceling must be in each term in the numerator and denominator. for example.. x+3/x^2 you cannot cancel an x because there is no x with the 3

so same here.. you cannot cancel x^2 because only a single power x term is in the numerator's 2nd term.

we.. if you pull out 2x, you would be left with \[\frac{ x+3 }{ 5x^2 }\]

NO WAIT! \[\frac{ x + 3 }{ 5x^2 }\] Ach! You typed it in before me. Oh well. Thank you, you have been very helpful!
