Answer:

The vertex of a quadratic equation corresponds to the point where the maximum or minimum value is located.

If the function has a positive leading coefficient, the vertex corresponds to the minimum value.

If it has a negative leading coefficient,  the vertex corresponds to the maximum valuevalue

If the vertex is located at

(–2, 0)

The possibilities are

y =  (x-2)^2

or,

y = - (x-2)^2

Since the problem tells us the answer, we adopt the positive values

Answer:

y =  (x-2)^2

Answer:

y=(x+2)^2

Step-by-step explanation:

A graph that is a parabola with a vertex at (–2, 0)

Vertex form of parabola equation is

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

where (h,k) is the vertex

WE are given with vertex (-2,0)

(-2,0) is (h,k)

h=-2 and k=0

Plug the value in vertex form of equation. Lets take a=1

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

Equation becomes y=1(x-(-2))^2 + 0

y=(x+2)^2

AURORKA [14]
1.  Reduce  <span>3x2-6x-240   to    x^2 - 2x - 80

2.  Use " ^ " to indicate exponentiation

3.  Factor  </span>x^2 - 2x - 80 using completing the square:

     x^2 - 2x + 1^2 - 1^2 - 80

         (x+1)^2 - 1  - 80
          (x+1)^2 - 81
          (x+1)^2 - 9^2  = (x+1-9)(x+1 +9), or (x-8)(x+10)

Final answer, with all factors shown:      3(x-8)(x+10)

What is the simplified of this ?
Hatshy [7]

Answer:

The correct answer is A) x^6y^8

Step-by-step explanation:

The easiest way to find this is to first square the second term.

(-x^2y^3)^2 = (x^4y^6)

Now we multiply that by the first parenthesis.

(x^2y^2)(x^4y^6) = x^6y^8
