3x(2x-1)+4x=13
We move all terms to the left:
3x(2x-1)+4x-(13)=0
We add all the numbers together, and all the variables
4x+3x(2x-1)-13=0
We multiply parentheses
6x^2+4x-3x-13=0
We add all the numbers together, and all the variables
6x^2+x-13=0
a = 6; b = 1; c = -13;
Δ = b2-4ac
Δ = 12-4·6·(-13)
Δ = 313
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{-(1)-\sqrt{313}}{2*6}=\frac{-1-\sqrt{313}}{12} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{313}}{2*6}=\frac{-1+\sqrt{313}}{12} $
