Respuesta :

3x^2 + 4x + 8 + 2x^2 - 6x + 3

 to give result as 9x^2 -2x - 53x^2 + 4x + 8 + 2x^2 - 6x + 3 = 5x^2 - 2x + 11so9x^2 -2x - 5 - (5x^2 - 2x + 11)= 9x^2 -2x - 5 -  5x^2 +  2x - 11= 4x^2 -16

answer expression (4x^2 -16)

must be added to the sum of (3x^2 + 4x + 8) and (2x^2 - 6x + 3) to give the result as (9x^2 - 2x - 5)

don't forget to make me the brainiest

y∧2+5y-1 and 3y∧2-2y+4 to give 2y∧2+7y-2 = (4x^2 -16)
