(6x+4)(3x+2)=84
We move all terms to the left:
(6x+4)(3x+2)-(84)=0
We multiply parentheses ..
(+18x^2+12x+12x+8)-84=0
We get rid of parentheses
18x^2+12x+12x+8-84=0
We add all the numbers together, and all the variables
18x^2+24x-76=0
a = 18; b = 24; c = -76;
Δ = b2-4ac
Δ = 242-4·18·(-76)
Δ = 6048
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{6048}=\sqrt{144*42}=\sqrt{144}*\sqrt{42}=12\sqrt{42}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(24)-12\sqrt{42}}{2*18}=\frac{-24-12\sqrt{42}}{36} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(24)+12\sqrt{42}}{2*18}=\frac{-24+12\sqrt{42}}{36} $
