Which expression represents the product of x^3 +2x - 1 and x^4 -x^3 +3?

Answer:
Option C
The answer is
x⁷ - x⁶ + 2x⁵ - 3x⁴ + 4x³ + 6x - 3
Step-by-step explanation:
(x³ + 2x - 1) × (x⁴ - x³ + 3)
x⁷ - x⁶ + 3x³ + 2x⁵ - 2x⁴ + 6x - x⁴ + x³ - 3
x⁷ - x⁶ + 3x³ + x³ + 2x⁵ - 2x⁴ - x⁴ + 6x - 3
x⁷ - x⁶ + 4x³ + 2x⁵ - 3x⁴ + 6x - 3
x⁷ - x⁶ + 2x⁵ - 3x⁴ + 4x³ + 6x - 3
Thus, The answer is
x⁷ - x⁶ + 2x⁵ - 3x⁴ + 4x³ + 6x - 3
