22=2+37x+16x^2

Solution for 22=2+37x+16x^2 equation:

22=2+37x+16x^2

We move all terms to the left:

22-(2+37x+16x^2)=0

We get rid of parentheses

-16x^2-37x-2+22=0

We add all the numbers together, and all the variables

-16x^2-37x+20=0

a = -16; b = -37; c = +20;
Δ = b2-4ac
Δ = -372-4·(-16)·20
Δ = 2649
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{-(-37)-\sqrt{2649}}{2*-16}=\frac{37-\sqrt{2649}}{-32}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-37)+\sqrt{2649}}{2*-16}=\frac{37+\sqrt{2649}}{-32}
