##### Apply division algorithm to find the quotient q(x) and remainder r(x) on dividing f(x) by g(x) in each of the following:(i) (ii) (iii) (iv)

(i) and

Degree of ; therefore degree of and degree of remainder is less than 2,

Let and

By applying division algorithm:

Dividend = Quotient× Divisor + Remainder

On substituting values in the above relation we get,

On comparing coefficients we get,

On solving above equations we get,

, , ,

On substituting these values for
