5+1.5x(2x-1)=0.5
We move all terms to the left:
5+1.5x(2x-1)-(0.5)=0
We add all the numbers together, and all the variables
1.5x(2x-1)+4.5=0
We multiply parentheses
2x^2-1x+4.5=0
a = 2; b = -1; c = +4.5;
Δ = b2-4ac
Δ = -12-4·2·4.5
Δ = -35
Delta is less than zero, so there is no solution for the equation
