6c2+3=51

Solution for 6c2+3=51 equation:

6c^2+3=51

We move all terms to the left:

6c^2+3-(51)=0

We add all the numbers together, and all the variables

6c^2-48=0

a = 6; b = 0; c = -48;
Δ = b2-4ac
Δ = 02-4·6·(-48)
Δ = 1152
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1152}=\sqrt{576*2}=\sqrt{576}*\sqrt{2}=24\sqrt{2}$
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-24\sqrt{2}}{2*6}=\frac{0-24\sqrt{2}}{12}
=-\frac{24\sqrt{2}}{12}
=-2\sqrt{2}
$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+24\sqrt{2}}{2*6}=\frac{0+24\sqrt{2}}{12}
=\frac{24\sqrt{2}}{12}
=2\sqrt{2}
