X2-0.0289+0.17x=0

Solution for X2-0.0289+0.17x=0 equation:

X2-0.0289+0.17X=0

We add all the numbers together, and all the variables

X^2+0.17X-0.0289=0

a = 1; b = 0.17; c = -0.0289;
Δ = b2-4ac
Δ = 0.172-4·1·(-0.0289)
Δ = 0.1445
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{-(0.17)-\sqrt{0.1445}}{2*1}=\frac{-0.17-\sqrt{0.1445}}{2}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0.17)+\sqrt{0.1445}}{2*1}=\frac{-0.17+\sqrt{0.1445}}{2}
