Question

When 3x² +5x -P is divided by (x+2), remainder is 10.What is the value of P ?
a. 8
b. (-8)
c. 32
d. (-32)

Answer 1

Answer:

Let us assume x+2 = 0

then, x = - 2

Given, f (x) = 3x² + 5x + P

Now, substitute the value of x in f (x),

so, f (-2) = 3(-2)² + 5(-2) + P

= 12 + (-10) + P

= 12 - 10 + P

= 2 + P

from the question it is given that remainder is 10

so, 2 + P = 10

P = 10 - 2

P = 8

Hope this ans help you.
