Solution for 11x2-54x+48=0 equation:



11x^2-54x+48=0
a = 11; b = -54; c = +48;
Δ = b2-4ac
Δ = -542-4·11·48
Δ = 804
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{804}=\sqrt{4*201}=\sqrt{4}*\sqrt{201}=2\sqrt{201}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-54)-2\sqrt{201}}{2*11}=\frac{54-2\sqrt{201}}{22} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-54)+2\sqrt{201}}{2*11}=\frac{54+2\sqrt{201}}{22} $
