Simplifying 11 + -3b + b2 = 0 Solving 11 + -3b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '-11' to each side of the equation. 11 + -3b + -11 + b2 = 0 + -11 Reorder the terms: 11 + -11 + -3b + b2 = 0 + -11 Combine like terms: 11 + -11 = 0 0 + -3b + b2 = 0 + -11 -3b + b2 = 0 + -11 Combine like terms: 0 + -11 = -11 -3b + b2 = -11 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 = -11 + 2.25 Reorder the terms: 2.25 + -3b + b2 = -11 + 2.25 Combine like terms: -11 + 2.25 = -8.75 2.25 + -3b + b2 = -8.75 Factor a perfect square on the left side: (b + -1.5)(b + -1.5) = -8.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
