Question

Find the value of p the polynomial 3x 3 – 7x 2 – 9x + p
become exactly divisible by x – 3?

Answer 1

Answer:

Answer is P = 9

Step-by-step explanation:

x -3 =0

x=3

putting value of x in eq.

3x3 - 7x2 - 9x + P = 0 ( given)

3(3)3 - 7(3)2 -9×3 +p = 0

81 - 63 - 27 +p =0

-9 +p =0

P= 9
