3x(+2)=7x-6
We move all terms to the left:
3x(+2)-(7x-6)=0
We add all the numbers together, and all the variables
3x2-(7x-6)=0
We add all the numbers together, and all the variables
3x^2-(7x-6)=0
We get rid of parentheses
3x^2-7x+6=0
a = 3; b = -7; c = +6;
Δ = b2-4ac
Δ = -72-4·3·6
Δ = -23
Delta is less than zero, so there is no solution for the equation
