X*2x=10,84

Solution for X*2x=10,84 equation:

X*2X=10.84

We move all terms to the left:

X*2X-(10.84)=0

We add all the numbers together, and all the variables

X*2X-10.84=0

Wy multiply elements

2X^2-10.84=0

a = 2; b = 0; c = -10.84;
Δ = b2-4ac
Δ = 02-4·2·(-10.84)
Δ = 86.72
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{86.72}}{2*2}=\frac{0-\sqrt{86.72}}{4}
=-\frac{\sqrt{}}{4}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{86.72}}{2*2}=\frac{0+\sqrt{86.72}}{4}
=\frac{\sqrt{}}{4}
