Question

What must be added to 3x3 - 2 x ² + 5x+1 so that the sum may be 2x3 - x2 + 4x-1?​

Answer 1

Answer:

the equation must be added to 3x3 - 2 x ² + 5x+1 is x^2-x-4

Step-by-step explanation:

let the equation that sum with 3x3 - 2 x ² + 5x+1 is 2x3 - x^2 + 4x-1 = A

A.T.Q

3x3 - 2 x ² + 5x+1 + A = 2x3 - x^2 + 4x-1

= 9-2x^2+5x+1 + A + = 6 - x^2 + 4x-1

= 2x^2+5x+8 + A = -x^2 + 4x+5

= A = -x^2 + 4x+51-(-2x^2 + 5x+8)

= A = -x^2 + 4x+r+x^2 - 5x-8

= A = x^2-x-4
