<em><u>ANSWER</u></em>
My answer is in the photo above
C - 72 x 4
If using PEMDAS, you can already deduce the exponents and parenthesis. With these gone, you're left with multiplication and division and this is decided by which comes first from left to right. Thus, leaving you with the first multiplication problem presented.
Hope this helps!
You’re learning the definition of the derivative aren’t you. Just plug in x+h and do FOIL. Then multiply each term by -3 because of -3 infront of the square.
-3(x+h)^2 - 2(x+h) +4
-3[x^2 + 2xh + h^2] - 2x - 2h + 4
-3x^2 - 6xh - 3h^2 - 2x - 2h + 4
Your answer is D
