The rule is the number divided by 5
Name the two given polynomials as
f(x) = 19x³ + 44x²y + 17
g(x) = y³ - 11xy² + 2x²y - 13x³
Create the subtraction f(x) - g(x).
f(x)-g(x) = 19x³ + 44x²y + 17 - (y³ - 11xy² + 2x²y - 13x³)
= (19 + 13)x³ + (44 - 2)x²y + 11xy² - y³ + 17
= 32x³ - y³ + 42x²y + 11xy² + 17
Answer: D
Note that answer D has a typo. 11xy² is correct, but 11x²y is not.
