The mistake done is in multiplying the numerator values after Taking LCM.
Correct answer is
Step-by-step explanation:
We will first solve the expression and then identify the error.
Solving:
Finding LCM of (x-2) and (x+1) we get (x-2)(x+1)
So, the mistake done is in multiplying the numerator values after Taking LCM. x+1-(x-2) we get x+1-x+2 because (-)*(-) = + and (-)*(+)= -. So, we get
x-x+1+2 we know that x-x=0 and 1+2=3
So, correct answer is
