6x(x+4)=28
We move all terms to the left:
6x(x+4)-(28)=0
We multiply parentheses
6x^2+24x-28=0
a = 6; b = 24; c = -28;
Δ = b2-4ac
Δ = 242-4·6·(-28)
Δ = 1248
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{1248}=\sqrt{16*78}=\sqrt{16}*\sqrt{78}=4\sqrt{78}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(24)-4\sqrt{78}}{2*6}=\frac{-24-4\sqrt{78}}{12} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(24)+4\sqrt{78}}{2*6}=\frac{-24+4\sqrt{78}}{12} $
