Question

Which is equal to 11f/(2f+3)(f-4) + (f+6)/(2f+3)
/ <---This is fraction not division
a. f^2+13f-24/(2f+3)(f-4)
b. 22f^2+34f-6/(2f+3)(f-4)
c. f^2+f+24/(2f+3)(f-4)
d. 2f^2-3f-18/(2f+3)(f-4)

Please help! I don't know the steps to do this.  I thought I did but I guess I didn't.  Can you show me the steps?

You'd probably find this problem to be a bit easier if you'd draw out the fractions in question, rather than try to type them in as you've already done.  Or, use Equation, below.

$$ \frac{ 11f }{(2f+3)(f-4)  }+\frac{ f+6 }{ 2f+3 }$$
