56x^2+4x-63000=0

Solution for 56x^2+4x-63000=0 equation:

56x^2+4x-63000=0

a = 56; b = 4; c = -63000;
Δ = b2-4ac
Δ = 42-4·56·(-63000)
Δ = 14112016
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{14112016}=\sqrt{16*882001}=\sqrt{16}*\sqrt{882001}=4\sqrt{882001}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(4)-4\sqrt{882001}}{2*56}=\frac{-4-4\sqrt{882001}}{112}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(4)+4\sqrt{882001}}{2*56}=\frac{-4+4\sqrt{882001}}{112}
