    Here was the original expression. \[4x+3 \over x-5\] \[\times\]\[x-5 \over x+3\]

    This is what the question says, Use your understanding of multiplying and dividing fractions to rewrite the expressions below. Then look for "ones" and simplify. For each rational expression, also stadte any valuses of the varibles that would make the denomintaior zero. here is the full question... http://hotmath.com/help/bookindexes/cpm06/index.html?myhm=true#pid=cpm06_10_1_Classwork_10-15_412

    valuses of the varibles that would make the denomintaior zero would be x= -3

    valuse of the variable that would make the denomintaior zero would be x= -3

    this is the simplest 4x+3/x+3 nothing else you can do

    \[x \neq -3\] then the whole thing would be Undefined Slope, No Slope
