Full solution

Q. Subtract.\newline(9n2+6n)(n2+n)(9n^{2}+6n)-(n^{2}+n)
  1. Write Problem: Write down the problem.\newlineSubtract (n2+n)(n^2 + n) from (9n2+6n)(9n^2 + 6n).\newline(9n2+6n)(n2+n)(9n^2 + 6n) - (n^2 + n)
  2. Subtract Terms: Distribute the negative sign to the terms inside the parentheses.\newline(9n2+6n)n2n(9n^2 + 6n) - n^2 - n
  3. Distribute Negative: Combine like terms.\newline(9n2n2)+(6nn)(9n^2 - n^2) + (6n - n)\newline= 8n2+5n8n^2 + 5n
