7x^2-11x+10=16000
We move all terms to the left:
7x^2-11x+10-(16000)=0
We add all the numbers together, and all the variables
7x^2-11x-15990=0
a = 7; b = -11; c = -15990;
Δ = b2-4ac
Δ = -112-4·7·(-15990)
Δ = 447841
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{-(-11)-\sqrt{447841}}{2*7}=\frac{11-\sqrt{447841}}{14} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+\sqrt{447841}}{2*7}=\frac{11+\sqrt{447841}}{14} $
