(12x-9)(17x+3)=260
We move all terms to the left:
(12x-9)(17x+3)-(260)=0
We multiply parentheses ..
(+204x^2+36x-153x-27)-260=0
We get rid of parentheses
204x^2+36x-153x-27-260=0
We add all the numbers together, and all the variables
204x^2-117x-287=0
a = 204; b = -117; c = -287;
Δ = b2-4ac
Δ = -1172-4·204·(-287)
Δ = 247881
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-117)-\sqrt{247881}}{2*204}=\frac{117-\sqrt{247881}}{408} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-117)+\sqrt{247881}}{2*204}=\frac{117+\sqrt{247881}}{408} $
