Question

18) Check Whether the polynomial p(x)=2y+y+4-15 is a multiple of (2y-3).​

Answer 1

Answer:

by remainder theroem

2y-3=0

2y=3

y=3/2

Step-by-step explanation:

Now

On putting the valve of x in given equation

P(x)=2y+y+4-15

p(3/2)= 2×3/2+3/2+4-15

=2+3/2-11

=4+3-22/2

= -15/2

Answer 2

Answer:

Hemant sir 8917668285

Step-by-step explanation:

Let,

p(y)=2y 3 +2y 2+4y−15

g(y)=(2y−3)

=>2y−3=0

=>y= 23

If g(y) is a multiple of p(y),then p( 23 )=0

Now,

p( 23 )=0

=2( 23 ) 3 +( 23 ) 2 +4( 23 )−15

=2( 827 )+( 49 )+4( 23 )−15

= 427 + 49 +6−15

= 427+9+24−60

=0

Therefore,

g(y) is a multiple of p(y)

Hence, answer is 1
