Solution for 8b^2+3b+9-6-7b^2= equation:

Simplifying
8b2 + 3b + 9 + -6 + -7b2 = 0

Reorder the terms:
9 + -6 + 3b + 8b2 + -7b2 = 0

Combine like terms: 9 + -6 = 3
3 + 3b + 8b2 + -7b2 = 0

Combine like terms: 8b2 + -7b2 = 1b2
3 + 3b + 1b2 = 0

Solving
3 + 3b + 1b2 = 0

Solving for variable 'b'.

Begin completing the square.

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + 3b + -3 + b2 = 0 + -3

Reorder the terms:
3 + -3 + 3b + b2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + 3b + b2 = 0 + -3
3b + b2 = 0 + -3

Combine like terms: 0 + -3 = -3
3b + b2 = -3

The b term is 3b.  Take half its coefficient (1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
3b + 2.25 + b2 = -3 + 2.25

Reorder the terms:
2.25 + 3b + b2 = -3 + 2.25

Combine like terms: -3 + 2.25 = -0.75
2.25 + 3b + b2 = -0.75

Factor a perfect square on the left side:
(b + 1.5)(b + 1.5) = -0.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
