3x2-x-16=0

Solution for 3x2-x-16=0 equation:

3x^2-x-16=0

We add all the numbers together, and all the variables

3x^2-1x-16=0

a = 3; b = -1; c = -16;
Δ = b2-4ac
Δ = -12-4·3·(-16)
Δ = 193
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1)-\sqrt{193}}{2*3}=\frac{1-\sqrt{193}}{6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+\sqrt{193}}{2*3}=\frac{1+\sqrt{193}}{6}
