6x(12+13x)-11=1x=1x-(8-5x)-8x
We move all terms to the left:
6x(12+13x)-11-(1x)=0
We add all the numbers together, and all the variables
6x(13x+12)-1x-11=0
We add all the numbers together, and all the variables
-1x+6x(13x+12)-11=0
We multiply parentheses
78x^2-1x+72x-11=0
We add all the numbers together, and all the variables
78x^2+71x-11=0
a = 78; b = 71; c = -11;
Δ = b2-4ac
Δ = 712-4·78·(-11)
Δ = 8473
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{-(71)-\sqrt{8473}}{2*78}=\frac{-71-\sqrt{8473}}{156} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(71)+\sqrt{8473}}{2*78}=\frac{-71+\sqrt{8473}}{156} $
