alright. did you try factorizing the numerator?
OpenStudy (anonymous):
yeah... just cant figure it out
OpenStudy (anonymous):
okay. 3 times 2 is 6
3 minus 2 is 1
do you see where I am going with this?
OpenStudy (anonymous):

nooo the problem is written wrong
OpenStudy (anonymous):
(2a^ 2 +a + 3)÷ (a - 1)
OpenStudy (anonymous):
oops. are you sure it is +3 and not -3 at the end?
OpenStudy (anonymous):
if its -3 at the end then the problem makes sense
OpenStudy (anonymous):
yes

OpenStudy (anonymous):
(a-1)(2a+3)/(a-1)=
2a+3
OpenStudy (anonymous):
okay. so then it makes sense. as I said, 2 times -3 = -6
and 3-2 = 1
can you take it from there?
OpenStudy (anonymous):
the a-1 factors divide off
OpenStudy (anonymous):
still lost
OpenStudy (anonymous):
okay, what did you get when you tried factoring?
and do you know how factoring works?
