Question

If x-2 divieded x^3 +px^2 +7x +9 then reminder is 19 find value of P​

Answer 1

Answer:

p = 1/2

Step by step explanation:

# Solve this with the reminder theorem.

x-2 = 0. x = 2.

# substitute x value in the expression and equate it to the reminder.

2^3 + p 2^2 + 9 = 19

8 + 4p + 9 = 19

4p = 19 - 17

4p = 2

p = 1/2 = 0.5
