5x2-24x+22=0

Solution for 5x2-24x+22=0 equation:

5x^2-24x+22=0

a = 5; b = -24; c = +22;
Δ = b2-4ac
Δ = -242-4·5·22
Δ = 136
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:

$\sqrt{\Delta}=\sqrt{136}=\sqrt{4*34}=\sqrt{4}*\sqrt{34}=2\sqrt{34}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-24)-2\sqrt{34}}{2*5}=\frac{24-2\sqrt{34}}{10}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-24)+2\sqrt{34}}{2*5}=\frac{24+2\sqrt{34}}{10}
