Simplify the expression: (w+5)^2

My answer: w^2+25

I don't thinks it's +25 but I do think it's +10 as 2x5=10.

you could always try a genrator on google.
tell me how you get on.

(w+5)^2 = (w+5)(w+5)

= w^2 + 10w + 25

you could have easily discovered your answer was wrong by substituting in a value for w, say w=1

(w+5)^2 = (1+5)^2 = 6^2 = 36
w^2+25 = 1+25 = 26
Bzzzzt!

To simplify the expression (w+5)^2, you can apply the exponent to each term inside the parenthesis, using the pattern (a+b)^2 = a^2 + 2ab + b^2. In this case, a = w and b = 5.

Using the formula, we have:
(w+5)^2 = w^2 + 2(w)(5) + 5^2

Simplifying further:
(w+5)^2 = w^2 + 10w + 25

Therefore, the simplified expression is w^2 + 10w + 25.
