1.2x(x-1.5)-1.9x=1.4x-16.5
We move all terms to the left:
1.2x(x-1.5)-1.9x-(1.4x-16.5)=0
We add all the numbers together, and all the variables
-1.9x+1.2x(x-1.5)-(1.4x-16.5)=0
We multiply parentheses
x^2-1.9x-1.5x-(1.4x-16.5)=0
We get rid of parentheses
x^2-1.9x-1.5x-1.4x+16.5=0
We add all the numbers together, and all the variables
x^2-4.8x+16.5=0
a = 1; b = -4.8; c = +16.5;
Δ = b2-4ac
Δ = -4.82-4·1·16.5
Δ = -42.96
Delta is less than zero, so there is no solution for the equation
