X*3x=897

Solution for X*3x=897 equation:

X*3X=897

We move all terms to the left:

X*3X-(897)=0

Wy multiply elements

3X^2-897=0

a = 3; b = 0; c = -897;
Δ = b2-4ac
Δ = 02-4·3·(-897)
Δ = 10764
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{10764}=\sqrt{36*299}=\sqrt{36}*\sqrt{299}=6\sqrt{299}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-6\sqrt{299}}{2*3}=\frac{0-6\sqrt{299}}{6}
=-\frac{6\sqrt{299}}{6}
=-\sqrt{299}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+6\sqrt{299}}{2*3}=\frac{0+6\sqrt{299}}{6}
=\frac{6\sqrt{299}}{6}
=\sqrt{299}
