Simplifying b2 + 3b + 40 = 0Factor Reorder the terms: 40 + 3b + b2 = 0Factor Anything times zero is zero. 40 + 3b + b2 = 0acortF Solving 40 + 3b + b2 = 0 Solving for variable 'b'. Begin completing the square. Move the constant term to the right: Add '-40' to each side of the equation. 40 + 3b + -40 + b2 = 0 + -40 Reorder the terms: 40 + -40 + 3b + b2 = 0 + -40 Combine like terms: 40 + -40 = 0 0 + 3b + b2 = 0 + -40 3b + b2 = 0 + -40 Combine like terms: 0 + -40 = -40 3b + b2 = -40 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 = -40 + 2.25 Reorder the terms: 2.25 + 3b + b2 = -40 + 2.25 Combine like terms: -40 + 2.25 = -37.75 2.25 + 3b + b2 = -37.75 Factor a perfect square on the left side: (b + 1.5)(b + 1.5) = -37.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
