Find the vertex: \(\large y = 5x^2 + 4x + 9\)
  • JA1
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?
Omg thank you soo much for helping me! i've been waiting for hours! \(\Large\sf\color{#f2f2f2}{LOL}\) So A=5, B=4 and C=9?

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

Yes very good.
