X^2-10000x-60000X=0

Solution for X^2-10000x-60000X=0 equation:

X^2-10000X-60000X=0

We add all the numbers together, and all the variables

X^2-70000X=0

a = 1; b = -70000; c = 0;
Δ = b2-4ac
Δ = -700002-4·1·0
Δ = 4900000000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{4900000000}=70000$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-70000)-70000}{2*1}=\frac{0}{2}
=0
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-70000)+70000}{2*1}=\frac{140000}{2}
=70000
