Answer:
3x³ + 2x² - x + 3
Step-by-step explanation:
AB = x²(3x + 2) = 3x³ + 2x²
AB - C = 3x³ + 2x² - (x - 3)
= 3x³ + 2x² - x + 3
= 3x³ + 2x² - x + 3 ← in standard form
Answer: d.) a perfect square

I got 6 for my answer, but I'm not 100% sure if I'm right.
6(2x-11)+15=21
12x-66+15=21
12x-51=21
+51 +51
12x=72
