2.65x2=4.11

Solution for 2.65x2=4.11 equation:

2.65x^2=4.11

We move all terms to the left:

2.65x^2-(4.11)=0

We add all the numbers together, and all the variables

2.65x^2-4.11=0

a = 2.65; b = 0; c = -4.11;
Δ = b2-4ac
Δ = 02-4·2.65·(-4.11)
Δ = 43.566
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{43.566}}{2*2.65}=\frac{0-\sqrt{43.566}}{5.3}
=-\frac{\sqrt{}}{5.3}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{43.566}}{2*2.65}=\frac{0+\sqrt{43.566}}{5.3}
=\frac{\sqrt{}}{5.3}
