X*19x=76

Solution for X*19x=76 equation:

X*19X=76

We move all terms to the left:

X*19X-(76)=0

Wy multiply elements

19X^2-76=0

a = 19; b = 0; c = -76;
Δ = b2-4ac
Δ = 02-4·19·(-76)
Δ = 5776
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{5776}=76$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-76}{2*19}=\frac{-76}{38}
=-2
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+76}{2*19}=\frac{76}{38}
=2
