(5y+1)2

Just multiply the 5y and the 1 by 2. It is the same as 2(5y+1), which you would generally see, only written a different way.

10y+2

To simplify the expression (5y+1)2, we need to apply the exponent to both terms inside the parentheses.

Step 1: Square the first term: (5y)2 = 25y^2
Step 2: Multiply the first term by the constant inside the parentheses: 25y^2 * 1 = 25y^2
Step 3: Multiply the constant inside the parentheses by the constant inside the parentheses: 1 * 1 = 1

Therefore, the simplified expression is 25y^2 + 1.
