Full solution

Q. Subtract.\newline(9d+8)−(d+1)(9d + 8) - (d + 1)
  1. Distribute negative sign: We have the expression (9d+8)−(d+1)(9d + 8) - (d + 1). The first step is to distribute the negative sign across the terms inside the parentheses.(9d+8)−(d+1)(9d + 8) - (d + 1)=9d+8−d−1= 9d + 8 - d - 1
  2. Combine like terms: Now, we combine like terms. The 9d9d and −d-d are like terms, as are 88 and −1-1. \newline9d−d+8−19d - d + 8 - 1\newline=(9d−d)+(8−1)= (9d - d) + (8 - 1)\newline=8d+7= 8d + 7
