Elaina simplified the algebraic expression below. hannah claimed that elaina did not finish the process. which answer shows the simplified expression that hannah expected?

3y^2+9y-y^2+9-2y-3 = (3y^2-y^2)+(9y-2y)+(9-3)

2y^2-7y+6

2y^2+7y+6

4y^2-7y+6

4y^2+7y+6

The answer which shows the simplified expression that Hannah expected is:

The simplified algebraic expression that is obtained by Elaina is:

As we could clearly observe that Elaina did not properly simplify the algebraic expression.

Elaina just combined the like terms but did not simplify them.

Hence, on simplifying this expression we get:

                Hence, the simplified expression is:

3x + 4y -25 =0 represents the amount of change sianna should recieve

answer is b
