3b-2b^2=6

Solution for 3b-2b^2=6 equation:

Simplifying
3b + -2b2 = 6

Solving
3b + -2b2 = 6

Solving for variable 'b'.

Reorder the terms:
-6 + 3b + -2b2 = 6 + -6

Combine like terms: 6 + -6 = 0
-6 + 3b + -2b2 = 0

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
3 + -1.5b + b2 = 0

Move the constant term to the right:

Add '-3' to each side of the equation.
3 + -1.5b + -3 + b2 = 0 + -3

Reorder the terms:
3 + -3 + -1.5b + b2 = 0 + -3

Combine like terms: 3 + -3 = 0
0 + -1.5b + b2 = 0 + -3
-1.5b + b2 = 0 + -3

Combine like terms: 0 + -3 = -3
-1.5b + b2 = -3

The b term is -1.5b.  Take half its coefficient (-0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
-1.5b + 0.5625 + b2 = -3 + 0.5625

Reorder the terms:
0.5625 + -1.5b + b2 = -3 + 0.5625

Combine like terms: -3 + 0.5625 = -2.4375
0.5625 + -1.5b + b2 = -2.4375

Factor a perfect square on the left side:
(b + -0.75)(b + -0.75) = -2.4375

Can't calculate square root of the right side.

The solution to this equation could not be determined.
