5x^2+0x-30=0

Solution for 5x^2+0x-30=0 equation:

5x^2+0x-30=0

We add all the numbers together, and all the variables

5x^2+x-30=0

a = 5; b = 1; c = -30;
Δ = b2-4ac
Δ = 12-4·5·(-30)
Δ = 601
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{601}}{2*5}=\frac{-1-\sqrt{601}}{10}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{601}}{2*5}=\frac{-1+\sqrt{601}}{10}
