Question

if the quotient obtioned on dividing 3x3+11x2+34x+106byx-3, 3x2+ax+b then find a, b and also the reminder​

Answer 1

By long division method,dividing the 3xcube+11xsquare+34x+106 by x minus 3,we get remainder=469

On comparing the quotient we get by dividing the polynomials,

Quotient=2xsquare+29x+121

We get,a=29and b=121

So,remainder=469

a=29

b=121
