(b + 8)(b - 1)
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
2a+2a-7b+7b =4a
It is a quadratic expression which can be factored to (7b+9)(8b-7) after dividing all terms by 2
7b-10 = -3
cosits 7B lol:-)
It is: 19b+7b = 26b
7b + 15= -34 First, 7b + 15 - 15 = -34 - 15 So, 7b = -49 Then, 7b/7 = -49/7 And finally, b = -7 So b = -7
