x^2+60x-7,200=0

Solution for x^2+60x-7,200=0 equation:

x^2+60x-7.200=0

We add all the numbers together, and all the variables

x^2+60x-7.2=0

a = 1; b = 60; c = -7.2;
Δ = b2-4ac
Δ = 602-4·1·(-7.2)
Δ = 3628.8
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{-(60)-\sqrt{3628.8}}{2*1}=\frac{-60-\sqrt{3628.8}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(60)+\sqrt{3628.8}}{2*1}=\frac{-60+\sqrt{3628.8}}{2}
