Question

Just a question about the problem, dont need the answer if you dont want to solve it, but would 15 be negative? Thats all, Thanks!


`f(x)=x^(2) +15x+3`

Answer 1

`x = -(15)/(2)`

Explanation:

Hello!

The formula for the AOS is given to you, and you simply have to plug in the information given by the equation.

Equation of a Parabola (Standard):
`y = ax^2 + bx + c`

Comparing it to our equation:

• a = 1
• b = 15
• c = 3

Plug it in to the AOS formula:

• 
  `x = (-b)/(2a)`
• 
  `x = (-15)/(2(1))`
• 
  `x = -(15)/(2)`

You only have to input 15 in to the correct box since the negative sign is already placed for you.
