x² + (a-3 )x – 2a² + 6a – 4 = 0\nx2 +ax-3x  = 2a2 -6a+4\n\nx= (-a +- sqrt(a2 +12))/2\nare roots of x\n(-a+sqrt(a2 + 12))/2  =  2 * (-a-sqrt(a2 + 12))/2\nas sqrt of any no is +ve\ncancel den. 2\n-a + sqrt(a2 + 12) = 2 * (-a-sqrt(a2+12))\na = -3sqrt(a2+12)\na2 = 9(a2 +12)\n8a2 = -12 * 9\na = sqrt(-27/2) = 3i * sqrt(0.5)

False... y has to be 2...\n(3,2) is a solution, but not (3,1).
