Question

4x3 – 3x2 + 2x – 4 on division by x+1/2 leaves remainder (A) 225 (B) 325 (C) 425− (D) 4
Please give the complete solution

Answer 1

21x + what ? or is it just 21x ?

Answer 2

Hint: f(x) when divided by 'a', leaves the remainder of f(a).

Answer 3

@hartnn that's exactly the same thing I was wondering. 21x + ?

Answer 4

that should be :
'Hint: f(x) when divided by 'x-a', leaves the remainder of f(a).'

Answer 5

so its x+1/2,

Answer 6

f(x) when divided by 'x-a', leaves the remainder of f(a).
so here its x+1/2, so what will you put in place of 'x' in f(x) to get the remainder ?

Answer 7

Yes.

Answer 8

"Hint: f(x) when divided by 'a', leaves the remainder of f(a)."
Nope. By the way, hartnn corrected it now.

Answer 9

u put x=a, if the divisor is x-a
what will u put x= ? when divisor is x+1/2 ?
