3x*x=2700

Solution for 3x*x=2700 equation:

3x*x=2700

We move all terms to the left:

3x*x-(2700)=0

Wy multiply elements

3x^2-2700=0

a = 3; b = 0; c = -2700;
Δ = b2-4ac
Δ = 02-4·3·(-2700)
Δ = 32400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{32400}=180$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-180}{2*3}=\frac{-180}{6}
=-30
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+180}{2*3}=\frac{180}{6}
=30
