Domain of the equation: 2)x!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

(+1/2)x-(1.15)=0

We add all the numbers together, and all the variables

(+1/2)x-1.15=0

We multiply parentheses

x^2-1.15=0

a = 1; b = 0; c = -1.15;
Δ = b2-4ac
Δ = 02-4·1·(-1.15)
Δ = 4.6
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)-\sqrt{4.6}}{2*1}=\frac{0-\sqrt{4.6}}{2}
=-\frac{\sqrt{}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{4.6}}{2*1}=\frac{0+\sqrt{4.6}}{2}
=\frac{\sqrt{}}{2}
