Solution for 5x^2-46x+8=0 equation:



5x^2-46x+8=0
a = 5; b = -46; c = +8;
Δ = b2-4ac
Δ = -462-4·5·8
Δ = 1956
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:
$\sqrt{\Delta}=\sqrt{1956}=\sqrt{4*489}=\sqrt{4}*\sqrt{489}=2\sqrt{489}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-46)-2\sqrt{489}}{2*5}=\frac{46-2\sqrt{489}}{10} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-46)+2\sqrt{489}}{2*5}=\frac{46+2\sqrt{489}}{10} $
