Question

find the remainder when the polynomial p (x)= 2 x cube minus 5 x square + 3 X + 7 is divided by (2 X + 1)​

Answer 1

2x-1=0

x=1/2

P(1/2)=2×[1/2]cube +3×[1/2]square -5×1/2 +7

P(1/2)=2/8 +3/4 -5/2 +7

=1/4 +3/4 -5/2+7

=4/4 -5/2+7

=-5/2+7

=-5+14/2

=9/2 Answer

Answer 2

Answer:

7/4

Step-by-step explanation:

2x+1=0

2x=-1

x=-1/2

=p(x) =2x^3-5x^2+3x+7

=p(-1/2)=-1/4-5/4-3(-1/2)+7

=-1-5-6/4+7

=7/4(remainder)
