24.8x^2=25x

Solution for 24.8x^2=25x equation:

24.8x^2=25x

We move all terms to the left:

24.8x^2-(25x)=0

a = 24.8; b = -25; c = 0;
Δ = b2-4ac
Δ = -252-4·24.8·0
Δ = 625
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{625}=25$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-25)-25}{2*24.8}=\frac{0}{49.6}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-25)+25}{2*24.8}=\frac{50}{49.6}
=1+0.4/49.6
