1.2x^2=0.8

Solution for 1.2x^2=0.8 equation:

1.2x^2=0.8

We move all terms to the left:

1.2x^2-(0.8)=0

We add all the numbers together, and all the variables

1.2x^2-0.8=0

a = 1.2; b = 0; c = -0.8;
Δ = b2-4ac
Δ = 02-4·1.2·(-0.8)
Δ = 3.84
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{3.84}}{2*1.2}=\frac{0-\sqrt{3.84}}{2.4}
=-\frac{\sqrt{}}{2.4}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{3.84}}{2*1.2}=\frac{0+\sqrt{3.84}}{2.4}
=\frac{\sqrt{}}{2.4}
