simplify (2x+y)^2

x=2 right?

help please

Since this is not an equation, we cannot determine the value of 2.

I don't know what they mean by simplify here. If you expand it out you get

4x^2 + 4xy + y^2

but that's not simpler, in my opinion. I think the problem as shown is not complete.

To simplify the expression (2x + y)^2, you need to expand it using the formula for expanding a binomial squared.

Step 1: Replace x with 2 in the expression.

(2(2) + y)^2

Simplifying this, we get:

(4 + y)^2

Step 2: Expand the binomial squared using the formula (a + b)^2 = a^2 + 2ab + b^2.

(a + b)^2 = a^2 + 2ab + b^2

In our case, a = 4 and b = y. Substituting these values, we get:

(4)^2 + 2(4)(y) + (y)^2

Now, we can simplify this further:

16 + 8y + y^2

Therefore, the simplified expression of (2x + y)^2, where x = 2, is 16 + 8y + y^2.
