Question

4) Divide the first polynomial by the second polynomial & find the remainder using factor theorem. a) (X - 7x + 9). (x + 1) b) (2x2 – 2x + ax - a), (X - a) c) (54mº + 18m² - 27m + 5), (m - 3) + - - ​

Answer 1

Answer:

(a) Given, P(x) = x-7x+9 and q(x)= x+1

q(x)= x+1 = 0

x= -1

The remainder when P(x) is divided by q(x) is p(-1) ( By remainder theorem)

Thus,

P(x) = x-7x+9

P(-1)= -1-7(-1)+9

P(-1)=-1+7+9

P(-1)= 15 Answer

(c) 54m³(m-3)+18m²(m-3)-27m(m-3)+5(m-3)

54m4-162m³+18m³-54m²-27m²+81m+5m-15

54m4-144m³-81m²+86m-15
