Answer:
a. Quotient : 2x²+17x+71
Remainder : 280
b. Quotient : 4x²+9
Remainder : 0
Step-by-step explanation:
a.
2x² + 17x + 71
x-4 / 2x³ + 9x² + 3x -4
2x³ - 8x²
17x² + 3x
17x²-68x
71x-4
71x-284
280
Quotient : 2x²+17x+71
Remainder : 280
b.
4x² + 9
2x +3 / 8x³ + 27
8x³ + 27
0
Quotient : 4x²+9
Remainder : 0
