We get rid of parentheses

-56h^2+4h+6h+1=0

We add all the numbers together, and all the variables

-56h^2+10h+1=0

a = -56; b = 10; c = +1;
Δ = b2-4ac
Δ = 102-4·(-56)·1
Δ = 324
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{324}=18$
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(10)-18}{2*-56}=\frac{-28}{-112}
=1/4
$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(10)+18}{2*-56}=\frac{8}{-112}
=-1/14
