To find the correct option we need to calculate each of the given options.
Option (1):
\frac{x+2}{x-3} /  \frac{4}{x+2} =  \frac{x+2}{x-3} *  \frac{x+2}{4} =  \frac{(x+2)^2}{4(x-3)}

Option (2):
\frac{x+2}{x-3} *  \frac{4}{x+2} =  \frac{4}{x-3}

Option (3):
\frac{x+2}{x-3} - \frac{4}{x+2} = \frac{(x+2)^2-4(x-3)}{(x-3)(x+2)}

option (4)
\frac{x+2}{x-3} + \frac{4}{x+2} = \frac{(x+2)^2+4(x-3)}{(x-3)(x+2)}


So, the correct answer is option (2)

Please Please Solve Simplify The Equation
ivolga24 [154]
You distribute the number outside the parenthesis from the inside like the 3 to the q and the 3 to the 1 then the -4, add 1 and -4 which becomes -3 but then leave the one with the variable so it becomes 3q-3. do the same for each problem and the one with the fraction i suggest converting it to decimals so it's easier.
