Question

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

Answer 1

Answer:

Step-by-step explanation:

process is same number is differnt

Using remiander theorem, we find that dividing 3x3+ x2 -22x + 9 by 3x2 + 7x -6 leaves a remiander of -14x+21 . That is, if -14x+21 is added to 3x3+ x2 -22x + 9 the remainder is zero and is divisible.

Answer 2

Step-by-step explanation:

2x^2 -3x^2 - 8x = 2x + 1 x q + 10

x^2 - 8x = 2x + 1 x q + 10

x^2 -8x -10 = 2x + 1 x q

(x^2 -8x -10)/(2x+1) = q

solved it

then (q)= ur ans...
