X=2E-08x2-0.0007x+8.8604

Solution for X=2E-08x2-0.0007x+8.8604 equation:

X=2-08X^2-0.0007X+8.8604

We move all terms to the left:

X-(2-08X^2-0.0007X+8.8604)=0

We get rid of parentheses

08X^2+0.0007X+X-2-8.8604=0

We add all the numbers together, and all the variables

08X^2+1.0007X-10.8604=0

a = 08; b = 1.0007; c = -10.8604;
Δ = b2-4ac
Δ = 1.00072-4·08·(-10.8604)
Δ = 348.53420049
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1.0007)-\sqrt{348.53420049}}{2*08}=\frac{-1.0007-\sqrt{348.53420049}}{16}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1.0007)+\sqrt{348.53420049}}{2*08}=\frac{-1.0007+\sqrt{348.53420049}}{16}
