What is the first step in writing f(x) = 6x2 + 5 – 42x in vertex form?

factor 6 out of each term.
factor 6 out of the first two terms.
write the function in standard form.
write the trinomial as a binomial squared

Option 3rd is correct

Write the function in standard form.

Step-by-step explanation:

The standard form of the quadratic equation is given by:

As per the statement:

Given the function:

We have to find the first step writing f(x) vertex form.

Firstly, write the given function in standard form

by definition we have;

Therefore, the first step writing f(x) vertex form is, Write the function in standard form.

the correct answers i think are b. and d.

give me brainliest if it is correct!
