Find the value |

I'm back with the Olympiad series. While I can't offer regular classes on KZbin, I can provide you with ideas to enhance your problem-solving skills.
Best of luck for all the competitive exams!

a^2 - b^2 = (a+b)(a-b) Easy Right? Now, (a+b)^2 -(a-b)^2 = 4ab this is also easy! We need to know and practice everything! Best of luck!!!

You can also work it out as a multiplication between sum & difference of two terms: 105^2-95^2=(105-95)*(105+95)=10*200=2000

4*100*8=3200

3200

(108 + 92)(108 - 92) =3200
