The multiplication and division of the first integral of junior high school 4(m+n)^2·(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5 (-x)^5·(x^5)^1·x-(-x^4)^2·(-x)^2·(-x^6)

The multiplication and division of the first integral of junior high school 4(m+n)^2·(-m-n)^3-(m+n)(-m-n)^4+5(m+n)^5 (-x)^5·(x^5)^1·x-(-x^4)^2·(-x)^2·(-x^6)

Solution 4 (M + n) ^ 2 · (- m-n) ^ 3 - (M + n) (- m-n) ^ 4 + 5 (M + n) ^ 5 = - 4 (M + n) ^ 2 · (M + n) ^ 3 - (M + n) (M + n) ^ 4 + 5 (M + n) ^ 5 = - 4 (M + n) ^ 5 - (M + n) ^ 5 + 5 (M + n) ^ 5 = - 5 (M + n) ^ 5 + 5 (M + n) ^ 5 = 0 (- x) ^ 5 · (x ^ 5) ^ 1 · X - (- x ^ 4) ^ 2 · (...)
