Answer 3

yea bt um nt able to find the rt ans..

Answer 4

what remainder do you get?

Answer 5

x(a-1)+(b+5)

Answer 6

you should have got (a-1)x + b-5 , not b+5

Answer 7

yea rt bt nw hw to find the value of a n b?

Answer 8

right so, for the polynomial to perfectly divide the longer polynomial, remainder should be 0
so (a-1)x+(b-5) = 0
so, for a = 1 and b =5, the remainder is 0
