QUESTION: 6

The remainder when x3 + x2 - 2x +1 is divided by (x+1) is

Solution:
QUESTION: 7

For a polynomial p(x) = 2x4 - 3x3 + 2x2 + 2x-1 what is the remainder when it’s divided by x+4?

Solution:
QUESTION: 8

Find remainder when x3+1 is divided by x+1

Solution:
QUESTION: 9

Using Remainder theorem, find the remainder when 3x4 - 4x3 - 3x - 1 by x - 1

Solution:

By remainder theorem if x-1 = 0 then x=1 using it in equation we get p(x)= 3x⁴-4x³-3x-1 p(1)= 3x1⁴-4x1³-3x1-1 p(1)= 3-4-3-1 p(1)= -5

QUESTION: 10

In the division of a cubic polynomial p(x) by a linear polynomial, the remainder is p(-2).So, the divisor must be

Solution:
QUESTION: 11

If x³ + 9x +5 is divided by x, then remainder is

Solution:
QUESTION: 12

Find the remainder when P(x) = x2 - 2x is divided by x - 2

Solution:
QUESTION: 13

Find p(1/3) for p(t) = t2 – t + 2

Solution:

1/9-1/3+2 =1/9-3/9-18/9 =16/9

QUESTION: 14

Using Remainder Theorem find the remainder when x3 - x2 + x - 1 is divided by x - 1

Solution:
QUESTION: 15

P(x) is a polynomial in x, ‘a’ is a real number. If (x-a) is a factor of p(x), then p (a) must be​

Solution:

 If p(x) is a polynomial of degree n which is greater than or equal to one and a is any real number which will be the divisor, then there will be two conditions fulfilled: If p (a) =0, then x-a is a factor of that polynomial p(x). x-a would be the factor of the polynomial if the r(x) i.e. remainder is 0.
