Question

(2n3 - 3n4 + 7n) - (n3 - 8n4 - 7n)

Answer 1

Answer:

Step-by-step explanation:

(2n³ - 3n⁴ + 7n) - (n³ - 8n⁴ - 7n) = 2n³ - 3n⁴ + 7n - n³ + 8n⁴ + 7n

  {Here -1 is distributed }

                                                  = 2n³ - n³ - 3n⁴ + 8n⁴ + 7n + 7n

                   {Combine like terms}

                                                  = n³ + 5n⁴ + 14n
