Question 93406: subtract as indicated express the results in simplest form
5a - 12/a^2 - 8a + 15 - 3a - 2/a^2 - 8a + 15 Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! subtract as indicated express the results in simplest form
5a - 12/a^2 - 8a + 15 - (3a - 2)/a^2 - 8a + 15
-----------
The denominators are the same so subtract the numerators
and put the result over the common denominator:
----------
[5a-12-3a+2] / [a^2=8a+15]
= [2a-10] / [(a-5)(a-3)]
= [2(a-5)]/[(a_5)(a-3)]
= 2/(a-3)
