98n^2+0n-200=0

Solution for 98n^2+0n-200=0 equation:

98n^2+0n-200=0

We add all the numbers together, and all the variables

98n^2+n-200=0

a = 98; b = 1; c = -200;
Δ = b2-4ac
Δ = 12-4·98·(-200)
Δ = 78401
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-\sqrt{78401}}{2*98}=\frac{-1-\sqrt{78401}}{196}
$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{78401}}{2*98}=\frac{-1+\sqrt{78401}}{196}
