-443=-9.8x^2

Solution for -443=-9.8x^2 equation:

-443=-9.8x^2

We move all terms to the left:

-443-(-9.8x^2)=0

We get rid of parentheses

9.8x^2-443=0

a = 9.8; b = 0; c = -443;
Δ = b2-4ac
Δ = 02-4·9.8·(-443)
Δ = 17365.6
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{-(0)-\sqrt{17365.6}}{2*9.8}=\frac{0-\sqrt{17365.6}}{19.6}
=-\frac{\sqrt{}}{19.6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{17365.6}}{2*9.8}=\frac{0+\sqrt{17365.6}}{19.6}
=\frac{\sqrt{}}{19.6}
