Using Synthetic division and remainder theorem.
1. P(x) = 2x³-5x²-9x-8 : x-5
2. P(x) = x³- x -6 ; x-3
3. P(x) = x³+ 8x²+ x+ 6 ; x-4
correct answer with solutions = brainliest
wrong and nonsense answer = report
please i need help, because tomorrow is the deadline.

Answer:
1.2x³-9x-5x²-8
let x= 3
P(3)= 2x³-5x²-9x-8
= 2(3)³-5(3)²-9(3)-8
= 2(27)-5(9)-27-8
= 54-45-27-8
= -26
2.P(x) = x³- x -6 ; x-3
x³ + x² + x + 3
(-2)³ + (-2)² + (-2) +3
8 + 4 - 2 + 3
= 3
