Question

solve this maths question. (a-b-2c) (a-b+2c)​

Answer 1

Thanks for sending the question ; it gave me a lot of good (and ... (a+b+c)^2 = (a^2 +b^2+c^2)+2(ab+ac+bc) and so (ab+ac+bc)

Answer 2

Answer:

( a - b - 2c) (a - b + 2c)

= a^2 - ab + 2ac  - ab + b^2 - 2bc - 2ac +2bc - 2c^2 ( i just multiplied the polynomials)

= a^2 - 2ab + b^2 - 2c^2

hope it helps.....
