Use the technique of completing the square to transform the quadratic equation into the form (x + c)2 = a.
2x2 + 32x + 12 = 0
Thanks alot guys.
You are left with .....(I)
if you compare I and II, you should see that c = 8.
So you need to have , which is equal to
now if you look at equation (I) again, you already have .
To make this ,
you need to add 58 right?
Now put the above equation in the form of
