Answer:
C. 77x⁷ + 78x⁶ - 27x⁵
Explanation:
Operation of functions
f(x) g(x)
f(x) • g(x) = (11x³ - 3x²)(7x⁴ + 9x³)
Simplify or expand
(11x³ - 3x²)(7x⁴ + 9x³)
Expand the expression
11x³ × 7x⁴ + 11x³ × 9x³ - 3x² × 7x⁴ - 3x² × 9x³
Multiply
77x⁷ + 99x⁶ - 21x⁶ - 27x⁵
Combine like terms
77x⁷ + 78x⁶ - 27x⁵
Hope this helps and have a nice day
