To transform the quadratic equation into the equation form (x + p)2 = q we shall proceed as follows: 3+x-3x^2=9 putting like terms together we have: -3x^2+x=6 dividing through by -3 we get: x^2-x/3=-2 but c=(b/2a)^2 c=(-1/6)^2=1/36 thus the expression will be: x^2-x/3+1/36=-2+1/36 1/36(6x-1)²=-71/36
