Can someone show me the answer to this one. Please show me how you got the answer. Thanks

(b+2)/(b-4)-(B+6)/(b+3)
 


You need a common denominator, before you can subtract one algebraic fraction from another.

Do you know how to make both denominators the same?

 
multiply the first side by b+3 both numerator and denominator, also multiply the second side by b-4 both the denominator and numerator. to get the denominator as (b-4)(b+3). yes...I see. Never mind. I solved it. Thanks
