6b/a^2-b^2 + 3/b-a - 4/a+b = 6b/(a-b)(a+b) + 3/b-a - 4/a+b = 6b/(-2-3)(-2+3) + 3/(3+2) - 4/(-2+3) = 6b/-5 + 3/5 - 4/1 = 6*3/-5 + 3/5 - 4 = -18/5 + 3/5 - 4 = -15/5 - 4 = - 3 - 4 = -7
ответ: -7
-7
Объяснение:
6b/a^2-b^2 + 3/b-a - 4/a+b
6*3/((-2)^2-3^2) + 3/(3-(-2)) - 4/(-2+3)
18/(4-9) + 3/(3+2) - 4/(-2+3)
18/-5 + 3/5 - 4/1
18/-5 + 3/5 - 4
- (18/5) + 3/5 - 4
(-18+3)/5 - 4
-15/5 - 4
-3-4
