Answer 1

using reminder theorem find the reminder when p(x)=x3+3x2-5x+4is divided by(x-2)




P(x)=x3+3x2-5x+4
P(2)=x3+3x2-5x+4
(2)3+3(2)2-5(2)+4
8+12-10+4
==14
The answer is 14

Answer 2

x-2 =0
x = 2
p(x) = x3+ 3×2-5x+4
p(2) = (2)3 + 3×2 - 5 (2) + 4
p ( 2) = 6 + 6 - 10 + 4
p(2)= 6 + 6 - 6
p(2) = 6 + 0
= 6
x - 2 = 6 is reminder
