Question 37647: I am having problems trying to solve rational expressions with different denominators I am completely lost as how to solve this problem please help me.Thank you.
x-1 x+4
_____ + ________
x^- x- 12 x^+5x+6
the x^ like that mean that they are to the 2nd power Sorry but when I preview my question it gets jumbled up it should be x-1 over x to the 2nd power subract x subract 12 plus x+4 over x to the 2nd power plus 5x plus 6. Thank you again

now need to make the 2 denominators the same so we can then add the fractions...just like ANY fractions. The denominator needs to be (x-4)(x+3)(x+2). So:

At first glance, the numerator is not factorisable so leave it like this. Also, check my working just in case i have messed up: it is difficult keeping track of so much when written in code. But the process is correct.
