Answer» Given polynomial 2x 2 −3x+5 is DIVIDED by 2x−3 Then 2x−3=0 or x= 2 3 Replace x by 2 3 we get p(x)=2x 2 −3x+5 p( 2 3 )=2( 2 3 ) 2 −3( 2 3 )+5 ⇒p( 2 3 )= 4 18 − 2 9 +5 ⇒p( 2 3 )= 4 18−18+20 ⇒p( 2 3 )=5 THUS REMAINDER is 5 Then the value of polynomial 2x 2 −3x+5 is not zero by polynomial 2x−3 So 2x−3 is not the factor of polynomial 2x 2 −3x+5 |
