18x*x=1458

Solution for 18x*x=1458 equation:

18x*x=1458

We move all terms to the left:

18x*x-(1458)=0

Wy multiply elements

18x^2-1458=0

a = 18; b = 0; c = -1458;
Δ = b2-4ac
Δ = 02-4·18·(-1458)
Δ = 104976
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{104976}=324$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-324}{2*18}=\frac{-324}{36}
=-9
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+324}{2*18}=\frac{324}{36}
=9
