Question

What should be subtracted from 3x^3-5x^2-x+2 to get 4x^3+3x-5

Answer 1

Step-by-step explanation:

let we subtract z

(3x^3-5x^2+2)-z= 4x^3+3x-5

so z= -x^3-5x^2-3x7

Answer 2

Answer:  pls mark me brainliest

-x³ - 5x² - 4x + 7               or            - [x³ + 5x² + 4x - 7]

Step-by-step explanation:

Eq - 1 :  3x³ - 5x² - x + 2

Eq - 2 :  ?

Result : 4x³ + 3x - 5

∴ so, ( Eq - 1  -  Eq - 2 ) = Result

    ⇒  [3x³ - 5x² - x + 2]  -  [Eq - 2]  =  4x³ + 3x - 5

    ⇒  [3x³ - 5x² - x + 2]  -  [4x³ + 3x - 5]  =  [Eq - 2]

    ⇒   3x³ - 5x² - x + 2  -  4x³ - 3x + 5

    ⇒   -x³ - 5x² - 4x + 7               or            - [x³ + 5x² + 4x - 7]
