Answer:
1217 I think
Step-by-step explanation:
Hello, we know that for a and b real numbers
![a^2-b^2=(a-b)(a+b)](https://tex.z-dn.net/?f=a%5E2-b%5E2%3D%28a-b%29%28a%2Bb%29)
So,
![(2a-b)^2-(a-2b)^2=(2a-b-a+2b)(2a-b+a-2b)\\\\=(a+b)(3a-3b)\\\\\boxed{=3(a+b)(a-b)}](https://tex.z-dn.net/?f=%282a-b%29%5E2-%28a-2b%29%5E2%3D%282a-b-a%2B2b%29%282a-b%2Ba-2b%29%5C%5C%5C%5C%3D%28a%2Bb%29%283a-3b%29%5C%5C%5C%5C%5Cboxed%7B%3D3%28a%2Bb%29%28a-b%29%7D)
Thank you.
