If x² - 7x + a has a remainder 1 when divided by x + 1, then
The remainder when the polynomial p(x) = x3 -3x2 +2x-1 is divided by x-2 is
What is remainder when x3 – 2x2 + x + 1 is divided by (x -1)?
The remainder when x4 – 3x2 + 5x – 7 is divided by x + 1 is:
Correct Answer :- a
Explanation : x + 1 = 0
x = -1
x4 – 3x2 + 5x – 7
(-1)4 - 3(-1)2 + 5(-1) - 7 = 0
1 - 3 - 5 - 7
= -14
If x² - 7x + a has a remainder 1 when divided by x + 1, then
The remainder when x3 + x2 - 2x +1 is divided by (x+1) is
for finding the remainder we need to use remainder theorom
let p(x)=x3+x2-2x+1
Here, the divisor is x+1 for dividend p(x), we need to equate it to 0 and put that value of x in p(x).
−x+1=0
∴x=−1
p(−1)=(-1)3+(−1)2-2(−1)+1=3
Hence, remainder=3
For a polynomial p(x) = 2x4 - 3x3 + 2x2 + 2x-1 what is the remainder when it’s divided by x+4?
Using Remainder theorem, find the remainder when 3x4 - 4x3 - 3x - 1 by x - 1
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
In the division of a cubic polynomial p(x) by a linear polynomial, the remainder is p(-2).So, the divisor must be
If x³ + 9x +5 is divided by x, then remainder is
Find the remainder when P(x) = x2 - 2x is divided by x - 2
1/9-1/3+2 =1/9-3/9-18/9 =16/9
Using Remainder Theorem find the remainder when x3 - x2 + x - 1 is divided by x - 1
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
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.
