5=(0.5)x(2.0)V

Solution for 5=(0.5)x(2.0)V equation:

5=(0.5)x(2.0)

We move all terms to the left:

5-((0.5)x(2.0))=0

We add all the numbers together, and all the variables

-((0.5)x2)+5=0


We calculate terms in parentheses: -((0.5)x2), so:

(0.5)x2

We multiply parentheses

0.5x^2

Back to the equation:

-(0.5x^2)


We get rid of parentheses

-0.5x^2+5=0

a = -0.5; b = 0; c = +5;
Δ = b2-4ac
Δ = 02-4·(-0.5)·5
Δ = 10
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{10}}{2*-0.5}=\frac{0-\sqrt{10}}{-1}
=-\frac{\sqrt{}}{-1}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{10}}{2*-0.5}=\frac{0+\sqrt{10}}{-1}
=\frac{\sqrt{}}{-1}
