<h2>Answer:</h2>
  • The given equation is already in vertex form.
  • The vertex is located  at (7,-8)
<h2>Step-by-step explanation:</h2>

We Know that a standard form of a quadratic equation is given by:

                  y=ax^2+bx+c

where a,b and c are real numbers

and the vertex form is given by:

                 y=a(x-h)^2+k------------------(1)

where the vertex of the function is at: (h,k)

Here we have the function as:

          y=-3(x-7)^2-8

We observe that the equation matches the equation as in equation (1) ; such that a= - 3, h=7 and k= -8

Hence, the equation is already in vertex form and the vertex is at (7,-8)

Solve the equation x2-16x+54=0
kari74 [83]

Answer:

x1 = 8+√10, x2 = 8 -√10

Step-by-step explanation:

x² - 16x + 54 = 0

x = \frac{-b +/-\sqrt{b^{2} -4ac} }{2a} \\x = \frac{-(-16)+/-\sqrt{(-16)^{2} -4*1*54} }{2*1} \\\\\\x = \frac{16+/-\sqrt{(40)} }{2*1} = 8+/-\sqrt{10} \\\\x_{1} = 8+\sqrt{10}\\\\x_{2} =8-\sqrt{10}
