Write this equation in vertex form.
y = x^2 -12x +20

Step-by-step explanation:

The vertex form for a quadratic equation has the following form:

Where the vertice of the equation is the point (h, k)

To transform the equation in its vertex forms we must find its vertex.

Be a quadratic equation of the form:

Where a, b and c are real numbers, then the vertex of the equation will be:

For the given equation:

Therefore the vertice is:

Now we substitute x = 6 into the equation and find the value of k.

Therefore the vertice is: (6, -16)

And the equation is:

answer: for each 3 girls there is 2 boys . 3: 2
