X2 +8x+15

The detailed simplification is shown below:

Step-by-step explanation:

 Given,

            =    

           = .............simplify to get (x+3) and (x+5) as a common term.

           = ........... take common on numerator and denominator.

           = ...................cancel out the common term (x+3).

Hence,

                              =    

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
