### Instruction: What is the value of $(7+5)^2-(7-5)^2$?### Response: This problem involves some basic algebra and arithmetic, but I notice that there is a special pattern here that can make the calculation easier.
I recall that $(a+b)^2-(a-b)^2$ is always equal to $4ab$, where $a$ and $b$ are any numbers.
This is because $(a+b)^2-(a-b)^2 = a^2+2ab+b^2-(a^2-2ab+b^2) = 4ab$.
Therefore, in this problem, I can use this formula with $a=7$ and $b=5$.
