Need help with writing formula.

I used an Excel chart to derive a trendline formula. Now I need to enter the
formula into Excel to calculate other data. But, I can not figure out how to
enter the formula in a cell to get a correct answer.

Can anyone help me?

I need: y = -1E-10x2 + 3E-05x - 0.015 to be pasted into a cell and take an
"X" and produce a "Y."

Example: if X = 36,000, then Y should be 1.01 (or really close)
