Assuming your equation = 0, then:
b3+8b2+7b = 0
factor out b:
b(b2+8b+7) = 0
factor the squared term:
b(b+7)(b+1) = 0
So the answers are:
b = 0
b+7 = 0, b=-7
b+1 = 0, b=-1

6a plus 7b - 4a - 8b equals?
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
What is b if 7b plus 16 equals 5b plus 24?
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
-9 plus 7b equals 8b-7 what does b equal?
The equation can be rewritten as: (in Math, it is advised that the order of terms be arranged. In this equation, the term 7b comes before constant 9 which is the correct arrangement.)7b - 9 = 8b - 7To solve, transpose 8b to the left and 9 to the right so the equation becomes:7b -8b = 9 - 7-b = 2multiply both sides by -1 (to balance the equation) to make b positive:-1(-b) = -1(2)B= -2To check:7b - 9 = 8b - 77(-2) - 9 = 8(-2) - 7-14 -9 = -16 -7-23 = -23The answers in both sides of the equation is equal therefore, YOU have derived to a CORRECT answer...
What is the answer to -7b plus equals -51?
-58
How do you factor b2 - 7b plus 12?
b^2 - 7b + 12 = b^2 - 4b - 3b + 12 = b(b -4) -3(b - 4) = (b - 3)(b - 4)
What is the answer to b plus 7b?
8b
6a plus 7b - 4a - 8b equals?
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
What is b if 7b plus 16 equals 5b plus 24?
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
-9 plus 7b equals 8b-7 what does b equal?

1b2 plus 8b plus 7?
b^2 + 8b + 7 factors to (b + 7)(b + 1)
How do you factor 8b2-9b plus 1?
8b^2 -9b +1 8b^2 -8b -b +1 8b(b-1) - 1(b-1) (8b-1)(b-1)
What is 3a plus 2b-4a plus b?
The given expression can be simplified to: 3b-a
What is the answer of 23 plus 8b equals -42?
8b = -65 so b = -8.125
What is the answer to 7 b plus 15 equals -34?
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
What is the answer to -7b plus equals -51?
-58
What is b if 7b plus 15 equals -34?
7b + 15= -34 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7
What is 6b plus 21 equals 7b-21 equal to?
If: 6b+21 = 7b-21 Then: 6b-7b = -21-21 And: -b = -42 So: b = 42
