(-1/2)x+3=2x+7
We move all terms to the left:
(-1/2)x+3-(2x+7)=0
Domain of the equation: 2)x!=0We multiply parentheses
x!=0/1
x!=0
x∈R
-1x^2-(2x+7)+3=0
We get rid of parentheses
-1x^2-2x-7+3=0
We add all the numbers together, and all the variables
-1x^2-2x-4=0
a = -1; b = -2; c = -4;
Δ = b2-4ac
Δ = -22-4·(-1)·(-4)
Δ = -12
Delta is less than zero, so there is no solution for the equation
