Question

the polynomial ax³-3&2x²-5x³+a when divided by x-4 leaves p and q respectively, find the value of a if 2p-q

Answer 1

Given the first polynomial ax^3 -3 is divided by x-4 and left remainder p
so by remainder theorem p = a(4)^3 -3
p = 64a-3
Secondly 2x^2-5x^3+a is divided by x-4 and left q as remainder
q = 32-5(64)+a
= 288+a
now 2p -q is 2(64a-3) -(288+a)
132a -6 -288-a
131s -294

Answer 2

if 2p -q is somewhat else then u can put value of that instead of 0.

i have put 2p-q =0 because the question was incomplete.


it's best answer i know.
