(12x+3)(6x+9)=30x-60
We move all terms to the left:
(12x+3)(6x+9)-(30x-60)=0
We get rid of parentheses
(12x+3)(6x+9)-30x+60=0
We multiply parentheses ..
(+72x^2+108x+18x+27)-30x+60=0
We get rid of parentheses
72x^2+108x+18x-30x+27+60=0
We add all the numbers together, and all the variables
72x^2+96x+87=0
a = 72; b = 96; c = +87;
Δ = b2-4ac
Δ = 962-4·72·87
Δ = -15840
Delta is less than zero, so there is no solution for the equation
