3.5(x^2)=93.9

Solution for 3.5(x^2)=93.9 equation:

3.5(x^2)=93.9

We move all terms to the left:

3.5(x^2)-(93.9)=0

We add all the numbers together, and all the variables

3.5x^2-93.9=0

a = 3.5; b = 0; c = -93.9;
Δ = b2-4ac
Δ = 02-4·3.5·(-93.9)
Δ = 1314.6
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{1314.6}}{2*3.5}=\frac{0-\sqrt{1314.6}}{7}
=-\frac{\sqrt{}}{7}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{1314.6}}{2*3.5}=\frac{0+\sqrt{1314.6}}{7}
=\frac{\sqrt{}}{7}
