Question

Please answer with explanation

Answer 1

Hi ,

Let p( x ) = 8x⁴ - 8x² +7

By Remainder theorem ,

If p( x ) is divided by ( 2x + 1 ) then the

remainder is p ( -1/2 )

Now ,

p( -1/2 ) = 8 ( -1/2 )⁴ - 8 ( -1/2 )² + 7

= 8/16 - 8/4+ 7

= 1/2 - 2 + 7

= 5 + 1/2

= ( 10 + 1 )/2

= 11/2

Option ( A ) is correct.

I hope this helps you.
