Solution for 4d^2+9d-10=0 equation: 



4d^2+9d-10=0

a = 4; b = 9; c = -10;
Δ = b2-4ac
Δ = 92-4·4·(-10)
Δ = 241
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(9)-\sqrt{241}}{2*4}=\frac{-9-\sqrt{241}}{8}
$


$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+\sqrt{241}}{2*4}=\frac{-9+\sqrt{241}}{8}
$
