How did they get the vertex i need assistance

Step-by-step explanation:

The general formula of a quadratic equation is

while the general formula for finding the vertex is

first of all, you have to set the value of

From the given equation, a = 2; b = -12 and c = 13. therefore, x = -(-12)/2(2) = 12/4 = 3

The 3 gotten is the answer for the value of h. To get k, substitute the value of h into the quadratic equation.

k = 2(3)^2 - 12(3) + 13 = -5

Therefore, the Vertex is V(h,k) = V(3,-5)

step-by-step explanation:

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
