(-1/2)x-((-7.3))=0


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+7.3=0

We multiply parentheses

-1x^2+7.3=0

a = -1; b = 0; c = +7.3;
Δ = b2-4ac
Δ = 02-4·(-1)·7.3
Δ = 29.2
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{29.2}}{2*-1}=\frac{0-\sqrt{29.2}}{-2}
=-\frac{\sqrt{}}{-2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{29.2}}{2*-1}=\frac{0+\sqrt{29.2}}{-2}
=\frac{\sqrt{}}{-2}
