Answer. So, The no. is 7.

## What must be added to the polynomial 2×3 so that it leaves a remainder 10 when divided by 2x 1?

7 must be added to the polynomial 2x^3 – 3x^2 – 8x so that it leaves a remainder 10 when divided by 2x + 1.

## What must be added to 6x 5 5x 4 11x 3?

Hence 17x – 3 is added to 6×5+5×4+11×3-3×2+x+1,so that the polynomial so obtained is exactly divisible by 3×2-2x +4.

## What should be added to 6x 5 4x 4 27x 3?

what should be added to 6x^5+4x^4-27x^3-7x^2-27x-6 so that the resulting polynomial is exactly divisible by 2x^2-3. let us divide p(x) by . thus we must add to p(x).

## What must be added to 6x 4 8x 3?

Remainder = r(x) = Therefore, must be added to the polynomial f(x) = 6x^4 + 8x^3 + 18x^2 + 20x + 5 so that the resulting polynomial is divisible by g(x) = 3x^2 + 2x + 1.

## What must be added to so that it may be exactly divisible by?

So, 2x+5 must be added to f(x), so that the result is exactly divisible by x2+x−6.

## What must be added to x3?

Then , g(x)=0⇒x-3=0⇒x=3. By factor theorem , p (x) will be divisible by (x-3) if p (3) = 0. ⇒(15+k)=0⇒k=3. Hence , the required number to be added is 3 .

## What must be subtracted from the polynomial?

Hence, 3x+5 must be subtracted from the polynomial x3+13×2+35x+25 so that the resulting polynomial is exactly divisible by x2+11x+10. Was this answer helpful?

## What must be subtracted from 2x 2 3x 4 to get x2 2x 1?

Hence, the required expression is x² – 4x + 5.

## What must be subtracted from 16161 to get a perfect square?

Answer. 32 is the minimum number that can be substracted.

## What must be subtracted from (- 1 to get (- 6?

Answer. 5 must be subtracted from (-1) to get (-6).

## What should be subtracted from 2a 8b 10 to get 3a 7b 16?

5a +b -6 should be subtracted from 2a+8b+10 to get -3a+7b+16.
