(m^3 - n^3) / (m^2 - 2nm + n^2) =((m - n)(m^2 + mn + n^2)) / ((m - n)^2) =(m^2 + mn + n^2) / (m - n)
(-0.3)^2 - 16/12 + (-0.3)(1.6) + 3(-0.3) + 4(1.6) =
Упростим выражение m^3-n^3/m^2-2nm+n^2:0.09 - 4/3 - 0.48 - 0.9 + 6.4 =
-0.29
(m^3 - n^3) / (m^2 - 2nm + n^2) =
((m - n)(m^2 + mn + n^2)) / ((m - n)^2) =
(m^2 + mn + n^2) / (m - n)
