64-10x^2=0

Solution for 64-10x^2=0 equation:

64-10x^2=0

a = -10; b = 0; c = +64;
Δ = b2-4ac
Δ = 02-4·(-10)·64
Δ = 2560
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:

$\sqrt{\Delta}=\sqrt{2560}=\sqrt{256*10}=\sqrt{256}*\sqrt{10}=16\sqrt{10}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-16\sqrt{10}}{2*-10}=\frac{0-16\sqrt{10}}{-20}
=-\frac{16\sqrt{10}}{-20}
=-\frac{4\sqrt{10}}{-5}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+16\sqrt{10}}{2*-10}=\frac{0+16\sqrt{10}}{-20}
=\frac{16\sqrt{10}}{-20}
=\frac{4\sqrt{10}}{-5}
