(3x+4)x=18.4
We move all terms to the left:
(3x+4)x-(18.4)=0
We add all the numbers together, and all the variables
(3x+4)x-18.4=0
We multiply parentheses
3x^2+4x-18.4=0
a = 3; b = 4; c = -18.4;
Δ = b2-4ac
Δ = 42-4·3·(-18.4)
Δ = 236.8
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{-(4)-\sqrt{236.8}}{2*3}=\frac{-4-\sqrt{236.8}}{6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+\sqrt{236.8}}{2*3}=\frac{-4+\sqrt{236.8}}{6} $
