<PRE><B>Question 108379</B>
-1/2x²+4x-6=0
Multiply thru by -2 to get:
x^2-8x+12 = 0
Complete the square on the x terms and keep the equation balanced.
----------
x^2-8x = -12
x^2-8x+16 = -12+16
(x-4)^2 = 4
--------------
Take the square root of both sides to get:
x-4 = 2 or x-4 = -2
x = 6 or x = 2
