    Hello there user I have never met before, well you see first we need to know what the value of the terms are, so this is the standard equation: \[y = ax^{2} + bx + c\] so now we need to find out what A, B, and C are, so can you find that out for me?

    Yes perfect, ok so now we can use this very special formula we use for finding the vertex: \[\frac{ -b }{ 2(a) }\] So now can you substitute the numbers you got into this formula?

    \(\large\dfrac{ -4 }{ 2(5) }=\dfrac{-4}{10}=\dfrac{-2~~}{~5}~\huge?\)
