解答

展开

(m^{2} - m + n) (n + m + m^{2})

m^{4} + 2 m^{2} n - m^{2} + n^{2}

求解步骤

(m^{2} - m + n) (n + m + m^{2})

打开括号

= m^{2} n + m^{2} m + m^{2} m^{2} - mn - mm - m m^{2} + nn + nm + n m^{2}

化简

m^{2} n + m^{2} m + m^{2} m^{2} - mn - mm - m m^{2} + nn + nm + n m^{2} : m^{4} + 2 m^{2} n - m^{2} + n^{2}

= m^{4} + 2 m^{2} n - m^{2} + n^{2}
