x=-16x^2+128x

Solution for x=-16x^2+128x equation:

x=-16x^2+128x

We move all terms to the left:

x-(-16x^2+128x)=0

We get rid of parentheses

16x^2-128x+x=0

We add all the numbers together, and all the variables

16x^2-127x=0

a = 16; b = -127; c = 0;
Δ = b2-4ac
Δ = -1272-4·16·0
Δ = 16129
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{16129}=127$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-127)-127}{2*16}=\frac{0}{32}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-127)+127}{2*16}=\frac{254}{32}
=7+15/16
