-2(4x+1)=1/2x-2
We move all terms to the left:
-2(4x+1)-(1/2x-2)=0
Domain of the equation: 2x-2)!=0We multiply parentheses
x∈R
-8x-(1/2x-2)-2=0
We get rid of parentheses
-8x-1/2x+2-2=0
We multiply all the terms by the denominator
-8x*2x+2*2x-2*2x-1=0
Wy multiply elements
-16x^2+4x-4x-1=0
We add all the numbers together, and all the variables
-16x^2-1=0
a = -16; b = 0; c = -1;
Δ = b2-4ac
Δ = 02-4·(-16)·(-1)
Δ = -64
Delta is less than zero, so there is no solution for the equation
