Answer 2

To evaluate the expression (y+5)^2 - (y-3)(y+3) at y = 1 1/4 or y = 1.25, you simply substitute the value of y into the expression and perform the calculations. Here's how you can solve it step by step:

Step 1: Substitute the value of y into the expression.

Let y = 1.25.

(1.25 + 5)^2 - (1.25 - 3)(1.25 + 3)

Step 2: Simplify the expression using the order of operations (BIDMAS/BODMAS).

(6.25)^2 - (-1.75)(4.25)

Step 3: Perform the calculations within parentheses.

(6.25)^2 - (-7.4375)

Step 4: Calculate the square.

39.0625 - (-7.4375)

Step 5: Perform the subtraction.

39.0625 + 7.4375

Step 6: Calculate the final result.

46.5

Therefore, when y = 1 1/4 or y = 1.25, the value of the expression (y+5)^2 - (y-3)(y+3) is 46.5.
