When factoring 16x2 - 36, what is the first step?
A. It is a perfect square trinomial, so find the square root of the first and
last term.
B. It is a difference of squares so find the square roots for the first and last
term.
C. Find the greatest common factor (GCF).
D. The expression is prime it cannot be factored.

we conclude that the first step is to find the greatest common factor (GCF).

Hence, option C is correct.

Step-by-step explanation:

As 4 is the greatest common factor of the expression, so factor out common term 4:

i.e.

Thus, the first step is to find the greatest common factor (GCF)

Now, solving the remaining portion

as (2x+3) and (2x-3) are the factors of (4x²-9)

i.e. (4x²-9) = (2x+3) (2x-3)

Thus, the expression becomes

Therefore, we conclude that the first step is to find the greatest common factor (GCF).

Hence, option C is correct.

answer: no idea

step-by-step explanation: i just want points

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
