In the question 1) just put the value of x in the dividend to find the remainder

e.g if you are deviding the polynomial by x+1 then just make x+1=0 so that x=-1 and put the value of x i.e. -1 in place of x in the polynomial and the resulting number would be the remainder.

To find the quotient one may divide the polynomial by the given linear polynomial or may follow the principle of factorisation.

To find the values of a and b one has to follow the factorization by using the remainder theorem as well as the factorization theorem.

To find the GCD one has to factorise the polynomials and then find the common terms.

To find the LCM one has to first factorise the terms and then take the common terms and also the other terms which are not common and multiply to get the LCM.

1)

a) quotient =

remainder=-2b) quotient =

remainder=-8c) quotient =

remainder=0d) quotient =

remainder=27e) quotient =

remainder=-6f) quotient =

remainder=24g) it is same as (b)

a) quotient =

remainder=0Offline

2)

on dividing

we will get quotient=

on compairing with given quotient

=a=9 and b=6
