Domain of the equation: 3)x!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

-(+2/3)x-(-9.5)=0

We add all the numbers together, and all the variables

-(+2/3)x+9.5=0

We multiply parentheses

-2x^2+9.5=0

a = -2; b = 0; c = +9.5;
Δ = b2-4ac
Δ = 02-4·(-2)·9.5
Δ = 76
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{76}=\sqrt{4*19}=\sqrt{4}*\sqrt{19}=2\sqrt{19}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{19}}{2*-2}=\frac{0-2\sqrt{19}}{-4}
=-\frac{2\sqrt{19}}{-4}
=-\frac{\sqrt{19}}{-2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{19}}{2*-2}=\frac{0+2\sqrt{19}}{-4}
=\frac{2\sqrt{19}}{-4}
=\frac{\sqrt{19}}{-2}
