Answer:
x⁴ - x³ + 2x - 6
Step-by-step explanation:
Apparently i cannot write the equation needed so we will call it r(x) and the 2 given equations, a(x) and b(x) respectively
r(x) is the same as a(x) - b(x)
a(x) - b(x)
= x⁴ - 3x² + 5x - 7 -(x³ - 3x² + 3x -1)
= x⁴- x³ + (- 3x² + 3x²) + (5x - 3x) + (- 7 + 1)
= x⁴ - x³ + 2x - 6
