What is the first step in writing f(x) = 3x2 + 6x – 8 in vertex form? a. factor out 3 from each term. b. form a perfect square trinomial by keeping the value of the function equivalent. c. write the trinomial as a binomial squared. d. factor out 3 from the first two terms. explain your answer? no spam answers, if you spam your answers it's going mark your answer report. if your answer is wrong that's going mark your answer report. you! -charlie

  D. Factor out 3 from the first two terms.

Step-by-step explanation:

Vertex form is ...

  y = a(x -h)² +k

where (h, k) is the vertex and "a" is the vertical scale factor.

This equation expands to give ...

  y = ax² -2ahx + ah² +k

Factoring "a" from the terms involving x makes it easy to identify h and so finish putting the equation into vertex form. In this equation, that means the most appropriate first step is ...

  factor out 3 from the first two terms

D. Factor out 3 from the first two terms.

Step-by-step explanation:

According to the Vertex Formula [y = A(X - H)² + K], -H gives you the OPPOSITE terms of what they really are, but in this case, this would not qualify, since the question is asking something totally unique. So, since 3 is your "A", you factor that out, and since 6 is a multiple of 3, it is easy to work with. Anyway, you get this:

y = 3(x + 1)² - 11

I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.
