Determine the vertex
5) 7n^2- 40n + 25 = 0

How do I get the vertex?

vertex = (, - )

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

Then the x- coordinate of the vertex is

= -

7n² - 40n + 25 = 0 ← is in standard form

with a = 7, b= - 40 , thus

= - =

Substitute this value into the equation for corresponding y- coordinate

7( )² - 40( ) + 25

= 7( ) - + 25

= - + 25

= - + = -

vertex = ( , - )
