Divide all terms by -2:
4x2+4x+1 = 0
(2x+1)(2x+1) = 0
x = -1/2 and also x = -1/2
The quadratic equation has 2 equal roots.

How to make an equation equaling six or three.?
An equation never equals a number, but its solution often does.-- An equation with a solution of six: [ 3x - 14 = 4 ]-- An equation with a solution of three: [ 14 - 10x = -16 ]-- An equation with both solutions: [ x2 - 9x + 20 = 2 ]An equation that equals 6 is 10 - 4 = 6An equation that equals 3 is 10 - 7 = 3
