Question

please give answer.......​

Answer 1

Answer:

ANSWER IS - x^ 3 + 5x² + 6 x - 2

Step-by-step explanation:

SINCE IT IS WRITTEN  GREATER THAN, SO

(2 x^3  - 7x ^2 - 5x + 6 ) + other number =   (- x ^ 3 + 5 x ^2 + 6x - 2 )

other number =  (  - x ^3 - 2x ^ 2 + x + 4) - ( 2x^3 - 7x^2 -5x +6 )

- x ^ 3 - 2 x ^2 + x + 4  -  2 x^3 + 7x²  + 5x  -6  ( the interchange of signs in algebriac subtraction

- x ^ 3 - 2 x ^3  - 2x²   + 7x² + x +5x +4 -6

- x ^3 + 5x² + 6x - 2

so the final answer is - x³ + 5x²+ 6x - 2 .
