Question

1
What should be added to x^3+ 5x^2 + 7x + 3 so that it
is completely divisible by x^2 + 2x.​

Answer 1

Answer:

-x^3 - x^2 - 3x - 3

Step-by-step explanation:

(x^3 + 5x^2 + 7x + 3) + (-x^3 -x^2 - 3x - 3)

= 4x^2 + 4x

thus : 4x^2 + 4x   = 4x^2 + 2x

          x^2 + 2x

thus : answer is -x^3 - x^2 - 3x - 3
