Help with this formula please

[rudakropa]

Hello

I was wondering if anyone could please help me put this formula into excel?
I am very new to using excel and these complicated equations. Any help is greatly appreciated!


0.91 X² - (2n + 2.25)X+ n² = 0
0.84 X² - (2n + 4)X + n² = 0

X-unknown
n - known number (lets say 2)


(the forum made the X to the power of 2 into the above equations X<sup>2[/SUP. I hope that's correct?)

Did I mention I'm not the best i math...?

Cheers
Martyna</sup>
