Find the remainder when x^3+1 divided by x+1 using remainder theorem |
|
Answer» Given POLYNOMIAL x 3 +1 divided by (x+1) F(x)=x 3 +1 The polynomial divided by (x+1) Then put x=−1, we get f(−1)=(−1) 3 +1 ⇒f(−1)=−1+1 ⇒f(−1)=0 So, f(x)=x 3 +1 is divided by x+1 the remainder is zero. So, by Remainder THEOREM, we know that f(x)=x 3 +1 is divided by x+1 gives 0 as the remainder.Step-by-step explanation: |
