In simultaneous equations, at this level, you are often given two equations both containing an x and a y. For example:Equation1: y + 2x = 3Equation2: 4y + 2x = 8.The first step in approaching this is to t...
The first step would be to expand the second equation:(x-p)^2+qx^2-px-px+p^2+qthis simplifies to x^2-2px+p^2+qAfter this you examine the two equations and identify their similariti...
