-16x^2+170x=0

Solution for -16x^2+170x=0 equation:

-16x^2+170x=0

a = -16; b = 170; c = 0;
Δ = b2-4ac
Δ = 1702-4·(-16)·0
Δ = 28900
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{28900}=170$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(170)-170}{2*-16}=\frac{-340}{-32}
=10+5/8
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(170)+170}{2*-16}=\frac{0}{-32}
=0
