Question 78063
your equation is right...what was your method of solution?...factoring is probably the easiest


subtracting 12 from both sides gives x^2+4x-12=0...factoring gives (x-2)(x+6)=0...this means x=2 and x=-6


you mentioned taking the square root of a number...if you use the quadratic formula, the equation must equal zero before you start
