Wy multiply elements

480a*a-480=0

Wy multiply elements

480a^2-480=0

a = 480; b = 0; c = -480;
Δ = b2-4ac
Δ = 02-4·480·(-480)
Δ = 921600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{921600}=960$
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-960}{2*480}=\frac{-960}{960}
=-1
$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+960}{2*480}=\frac{960}{960}
=1
