Question

Find the remainder when the polynimals p(x):=2xcube-5xsquare+3x it is divided by 2x+1​

Answer 1

Step-by-step explanation:

By remainder theorem =p(x)=0

p(x)=2x+1

2x+1=0

2x=-1

x=-1/2

p(-1/2)=2(-1/2)^3-5(-1/2)^2+3(-1/2)

=2(-1/8)-5(1/4)-3(1/2)

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

=-1-5/4-3/2

=-6/4-3/2

=-3/2-3/2

=-3-3/2

=-6/2

Ans=-3..........Hope this will help you
