3x^2+x-5.29=0

Solution for 3x^2+x-5.29=0 equation:

3x^2+x-5.29=0

a = 3; b = 1; c = -5.29;
Δ = b2-4ac
Δ = 12-4·3·(-5.29)
Δ = 64.48
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{64.48}}{2*3}=\frac{-1-\sqrt{64.48}}{6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{64.48}}{2*3}=\frac{-1+\sqrt{64.48}}{6}
