Assuming your equation = 0, then:b3+8b2+7b = 0factor out b:b(b2+8b+7) = 0factor the squared term:b(b+7)(b+1) = 0So the answers are:b = 0b+7 = 0, b=-7b+1 = 0, b=-1
(-8 + b2) - (5 + b2) = -8 + b2 - 5 - b2 = -13
8b = e - 12n, possibly.
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
11a+11b
b^2 + 8b + 7 factors to (b + 7)(b + 1)

(8b + 7)(7b + 9)
b(b - 8)
(-8 + b2) - (5 + b2) = -8 + b2 - 5 - b2 = -13
8b = e - 12n, possibly.
8b = -65 so b = -8.125

8b^2 -9b +1 8b^2 -8b -b +1 8b(b-1) - 1(b-1) (8b-1)(b-1)
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
