The strategy involving
- identifying the clone which is relatively easy since clones are items which look EXACTLY the same.
- Let the clone by y (Substitution method)
Substitution:
Common Mistake! (Canceling y from each side of the equation; So What? : you will miss out 1 answer)
Correct Approach (Shift everything to left hand side so that right hand side is 0; So What? :Ready for factorization since it is a quadratic equation)
Remember we are interested in the unknown in the question (x) NOT y!
Check validity of answers by substituting values of x into the original given equation. Both values are acceptable.
