Question

Can you tell me which formula to use? I need to use either:
x = -b ± √b^2 -4ac / 2a
or
H(t) = -16^2 + vt + s

I have to solve the equation 0 = 2x^2 - 3x + 0.5

I've already multiplied out the decimals so now I have:
4x^2 - 6x + 1 = 0
I've multiplied 4 and 1 and now I have to find the product of 4 and sum of -6. I don't think there is one. If that was the case I would have to use x = -b ± √b^2 -4ac / 2a right?

But I'm not sure if I did the question right.
