18(2x-1)=6(x+2)3x
We move all terms to the left:
18(2x-1)-(6(x+2)3x)=0
We multiply parentheses
36x-(6(x+2)3x)-18=0
We calculate terms in parentheses: -(6(x+2)3x), so:We get rid of parentheses
6(x+2)3x
We multiply parentheses
18x^2+36x
Back to the equation:
-(18x^2+36x)
-18x^2+36x-36x-18=0
We add all the numbers together, and all the variables
-18x^2-18=0
a = -18; b = 0; c = -18;
Δ = b2-4ac
Δ = 02-4·(-18)·(-18)
Δ = -1296
Delta is less than zero, so there is no solution for the equation
