For the equation y = 2x^2 - 5x + 18, choose the correct application of the quadratic formula.

I believe it is A but I am not sure

A - x equals negative five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two

B - x equals five plus or minus the square root of negative five squared minus four times two times eighteen, all divided by two times two

C - x equals negative two plus or minus the square root of two squared minus four times negative five times eighteen, all divided by two times negative five

D - x equals two plus or minus the square root of two squared minus four times negative five times eighteen, all divided by two times negative five
