8d^2-968=0

Solution for 8d^2-968=0 equation:

8d^2-968=0

a = 8; b = 0; c = -968;
Δ = b2-4ac
Δ = 02-4·8·(-968)
Δ = 30976
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{30976}=176$
$d_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-176}{2*8}=\frac{-176}{16}
=-11
$
$d_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+176}{2*8}=\frac{176}{16}
=11
