(4x-2)(4x-2)=-6
We move all terms to the left:
(4x-2)(4x-2)-(-6)=0
We add all the numbers together, and all the variables
(4x-2)(4x-2)+6=0
We multiply parentheses ..
(+16x^2-8x-8x+4)+6=0
We get rid of parentheses
16x^2-8x-8x+4+6=0
We add all the numbers together, and all the variables
16x^2-16x+10=0
a = 16; b = -16; c = +10;
Δ = b2-4ac
Δ = -162-4·16·10
Δ = -384
Delta is less than zero, so there is no solution for the equation
