=> ![\sf 249^2 - 248^2](https://tex.z-dn.net/?f=%5Csf%20249%5E2%20-%20248%5E2)
<u>Using Formula</u> ![\sf a^2 - b^2 = (a+b)(a-b)](https://tex.z-dn.net/?f=%5Csf%20a%5E2%20-%20b%5E2%20%3D%20%28a%2Bb%29%28a-b%29)
<u><em>Where </em></u>
a = 249
b = 248
=> ![\sf (249+248)(249-248)](https://tex.z-dn.net/?f=%5Csf%20%28249%2B248%29%28249-248%29)
=> ![\sf (497)(1)](https://tex.z-dn.net/?f=%5Csf%20%28497%29%281%29)
=> 497
It is 8 because you divided it
Answer: p = 2
Step-by-step explanation:
To solve this problem, you first have to add 1 to each side of the equation, leaving you with 2p^2 = 8. Then you divide by 2 on both sides leaving you with p^2 = 4. After that, you take the square root of both sides, and because 4 is a perfect square, you get p = 2 as your final answer.
