help please...

OpenStudy (anonymous):

|dw:1407303276032:dw| Multiply the fractions and reduce to lowest terms

OpenStudy (dumbcow):

wow its already factored for you... ok start by cancelling like terms

OpenStudy (anonymous):

thats where i get confuse..do i cancel the 3 and x and 1?

OpenStudy (dumbcow):

?? no dont separate the factors, for example there is a (x+3) on top and a (x+3) on bottom so the factor (x+3) cancels

OpenStudy (anonymous):

i need to see it so i can understand it

OpenStudy (princeharryyy):

(x+1)(x+1)(x-3)/((x+1)(x+5)(x+3)) - (x+3)(x+3)(x+5)/((x+1)(x+5)(x+3)) make the denominator same in both the questions and solve the numerators to get the above factors

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

|dw:1407305144030:dw| this is what i got

OpenStudy (princeharryyy):

what were ur num after solving

OpenStudy (mokeira):

\[[x+3](x+3)(x+5)+[x+1](x+1)(x-3)\]

OpenStudy (anonymous):

\[\frac{(x+1) (x-3)}{(x+3) (x+5)}-\frac{x+3}{x+1}=\frac{6}{x+3}-\frac{16}{x+5}-\frac{2}{x+1} \]

OpenStudy (mokeira):

\[[x ^{3}-x ^{2}-5x-3]+[x ^{3}+11x ^{2}+39x+45]\] open up the brackets and simplify \[10x ^{2}+34x+42\]

OpenStudy (mokeira):

That is the answer

OpenStudy (anonymous):

i did everything yall showed me problem...the answer i got isnt in the options..so im doing something wrong dont think im trying i am i jst suck at algebra badly |dw:1407306380664:dw|

OpenStudy (anonymous):

*dont think im not trying i am

OpenStudy (princeharryyy):

check out the equation in the ques again

OpenStudy (dumbcow):

wow guys this isn't that complicated the (x+3) cancels , the (x+1) cancels leaving --> x-3/x+5

OpenStudy (anonymous):

ok i understood tht now.. i saw what i did wrong i didnt cancel out the x+3

OpenStudy (dumbcow):

@robtobey , this is multiplying not subtracting (i know the picture is deceiving)
