Suppose f(x) -6x^3 +11x^2 +kx+15. The remainder of the division of f(x) by (x + 2) is 5. What is the remainder when you divide by (x-3)? A. 280
B. 34
C. 285
D. -34

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
