Answer:
mn(x) = 5x³ + 9x² + 15x + 27
Step-by-step explanation:
mn(x) = m(x) × n(x)
mn(x) = (x² + 3)(5x + 9)
We can evaluate this expression by using the FOIL method.
First terms: x² × 5x = 5x³
Outer terms: x² × 9 = +9x²
Inner terms: 3 × 5x = +15x
Last terms: 3 × 9 = +27
mn(x) = 5x³ + 9x² + 15x + 27
