Use the method of completing the square to transform the quadratic equation into the equation form (x + p)2 = q. 3 + x - 3x2 = 9 a) (x - 1 6 )2 = 71 36 b) (x - 1 3 )2 = 71 36 c) (x - 1 6 )2 = - 71 36 eliminate d) (x - 1 3 )2 = - 71 36

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

the answer is:
1/36(6x-1)²=-71/36

X=14 hope it !
