What algebraic expression must be subtracted from the sum of y∧2+5y-1 and 3y∧2-2y+4 to give 2y∧2+7y-2 as a result? , i need with this ill give 99 points for this.

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

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
