172x-16x^2=0

Solution for 172x-16x^2=0 equation:

172x-16x^2=0

a = -16; b = 172; c = 0;
Δ = b2-4ac
Δ = 1722-4·(-16)·0
Δ = 29584
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{29584}=172$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(172)-172}{2*-16}=\frac{-344}{-32}
=10+3/4
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(172)+172}{2*-16}=\frac{0}{-32}
=0
