0=2x^2-24n+80
How do I find the vertex of the problem above by completing the square method

( 0 , 10/ 3 )

Step-by-step explanation:

Get the equation in the form y = ax2 + bx + c.

Calculate -b / 2a. This is the x-coordinate of the vertex.

To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

After following these steps, you have your x and y coordinates of the vertex, so you have your vertex. Not too bad, huh? We see that the vertex of a quadratic equation, y = ax2 + bx + c, is the following point.

(-b / 2a, a(-b / 2a)2 + b(-b / 2a) + c)

Answer :-2x2 - 24x - 80  =   -2 • (x2 + 12x + 40)
