Find the vertex: $$\large y = 5x^2 + 4x + 9$$

2. 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?

3. thomaster

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?

4. JA1

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?

5. thomaster

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

6. JA1

Yes very good.
