20x+(450-x)14x=7.320
We move all terms to the left:
20x+(450-x)14x-(7.320)=0
We add all the numbers together, and all the variables
20x+(-1x+450)14x-(7.32)=0
We add all the numbers together, and all the variables
20x+(-1x+450)14x-7.32=0
We multiply parentheses
-14x^2+20x+6300x-7.32=0
We add all the numbers together, and all the variables
-14x^2+6320x-7.32=0
a = -14; b = 6320; c = -7.32;
Δ = b2-4ac
Δ = 63202-4·(-14)·(-7.32)
Δ = 39941990.08
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{-(6320)-\sqrt{39941990.08}}{2*-14}=\frac{-6320-\sqrt{39941990.08}}{-28} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6320)+\sqrt{39941990.08}}{2*-14}=\frac{-6320+\sqrt{39941990.08}}{-28} $
