Question

Q.15) Using Remainder theorem find the remainder when the following polynomial is divided by X+2. * 3x2 + x +7​

Answer 1

Step-by-step explanation:

Remainder Theorem states that the remainder of the division of a polynomial f(x) by a linear polynomial (x−a) is f(a) or in other words (x−a) is divisor of f(x) if and only if f(a)=0

Here a=−2

Let p(x)=3x2+x+7

Remainder is when you put x=−2 in p(x) i.e. p(−2)

p(−2)=3(−2)2+(−2)+7

          =17

⇒p(−2)=17

Answer 2

Answer:

Step-by-step explanation:

6x²+2x+7.
