3=13x*0.5x
We move all terms to the left:
3-(13x*0.5x)=0
We add all the numbers together, and all the variables
-(+13x*0.5x)+3=0
We get rid of parentheses
-13x*0.5x+3=0
Wy multiply elements
0x^2+3=0
We add all the numbers together, and all the variables
x^2+3=0
a = 1; b = 0; c = +3;
Δ = b2-4ac
Δ = 02-4·1·3
Δ = -12
Delta is less than zero, so there is no solution for the equation
