94.2=c2(3.14)

Solution for 94.2=c2(3.14) equation:

94.2=c2(3.14)

We move all terms to the left:

94.2-(c2(3.14))=0


We calculate terms in parentheses: -(c2(3.14)), so:

c2(3.14)

We multiply parentheses

3.14c^2

Back to the equation:

-(3.14c^2)


We get rid of parentheses

-3.14c^2+94.2=0

a = -3.14; b = 0; c = +94.2;
Δ = b2-4ac
Δ = 02-4·(-3.14)·94.2
Δ = 1183.152
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{1183.152}}{2*-3.14}=\frac{0-\sqrt{1183.152}}{-6.28}
=-\frac{\sqrt{}}{-6.28}
$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{1183.152}}{2*-3.14}=\frac{0+\sqrt{1183.152}}{-6.28}
=\frac{\sqrt{}}{-6.28}
