Question 609547
<font face="Times New Roman" size="+2">

You have two expressions in *[tex \LARGE x] each of which is equal to *[tex \LARGE y].  They can't both be equal to *[tex \LARGE y] without being equal to each other, can they?  Set the two expressions in *[tex \LARGE x] equal to each other, collect like terms all in the LHS leaving the resulting quadratic trinomial in *[tex \LARGE x] equal to zero.  Solve the quadratic for its two roots, if they exist.  Hint:  The resulting quadratic is factorable over the integers.

My calculator said it, I believe it, that settles it
