Write p(x) = 21 + 24x + 6x2 in vertex form.

ANSWER

EXPLANATION

The given function is

We make the coefficient of unity by factoring out of the last two terms to obtain;

We now add and subtract half the coefficient of multiplied by a factor of 6 to obtain;

We now factor 6 out of the last two terms to get;

The quadratic trinomial in the parenthesis is now a perfect square.

Hence the vertex form of the polynomial is

y=20x

this cant be answered without the graph. you may need to add it.
