1.7x2=0.7x2+26.2

Solution for 1.7x2=0.7x2+26.2 equation:

1.7x^2=0.7x^2+26.2

We move all terms to the left:

1.7x^2-(0.7x^2+26.2)=0

We get rid of parentheses

1.7x^2-0.7x^2-26.2=0

We add all the numbers together, and all the variables

x^2-26.2=0

a = 1; b = 0; c = -26.2;
Δ = b2-4ac
Δ = 02-4·1·(-26.2)
Δ = 104.8
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{104.8}}{2*1}=\frac{0-\sqrt{104.8}}{2}
=-\frac{\sqrt{}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{104.8}}{2*1}=\frac{0+\sqrt{104.8}}{2}
=\frac{\sqrt{}}{2}
