5x2-32x+16=0

Solution for 5x2-32x+16=0 equation:

5x^2-32x+16=0

a = 5; b = -32; c = +16;
Δ = b2-4ac
Δ = -322-4·5·16
Δ = 704
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:

$\sqrt{\Delta}=\sqrt{704}=\sqrt{64*11}=\sqrt{64}*\sqrt{11}=8\sqrt{11}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-32)-8\sqrt{11}}{2*5}=\frac{32-8\sqrt{11}}{10}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-32)+8\sqrt{11}}{2*5}=\frac{32+8\sqrt{11}}{10}
