Problem

Simplify the expression \$ (4y^2) + (7y^2) \$.

2

Step

The given expression is

\$ (4y^2) + (7y^2)\$

3

Hint

Combine like terms. Like terms are terms that have the same variable raised to the same power. In this case, both terms have the variable y raised to the power of 2.

4

Step

Add the coefficients of the like terms:

\$( 4 + 7) y^2\$

5

Step

Perform the addition operation:

\$11 (y)^2\$

6

Solution

So, the simplified expression is \$11(y^2)\$.

8

Choice-A

The response is inaccurate as the simplified form should be \$11 y^2\$, not \$11 y^3\$

Wrong \$11 y^3\$

9

Choice-B

The provided solution is wrong as the simplified form should be \$11 y^2\$, not \$15 y^2\$

Wrong \$15 y^2\$

10

Choice-C

This STEP is incorrect because the simplified expression is \$11 y^2\$, not \$15 y^3\$

Wrong \$15 y^3\$

11

Choice-D

The simplified expression, \$11 y^2\$, validates this step as being correct
