Simplifying 4b2 + -12b + 39 = 0 Reorder the terms: 39 + -12b + 4b2 = 0 Solving 39 + -12b + 4b2 = 0 Solving for variable 'b'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 9.75 + -3b + b2 = 0 Move the constant term to the right: Add '-9.75' to each side of the equation. 9.75 + -3b + -9.75 + b2 = 0 + -9.75 Reorder the terms: 9.75 + -9.75 + -3b + b2 = 0 + -9.75 Combine like terms: 9.75 + -9.75 = 0.00 0.00 + -3b + b2 = 0 + -9.75 -3b + b2 = 0 + -9.75 Combine like terms: 0 + -9.75 = -9.75 -3b + b2 = -9.75 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 = -9.75 + 2.25 Reorder the terms: 2.25 + -3b + b2 = -9.75 + 2.25 Combine like terms: -9.75 + 2.25 = -7.5 2.25 + -3b + b2 = -7.5 Factor a perfect square on the left side: (b + -1.5)(b + -1.5) = -7.5 Can't calculate square root of the right side. The solution to this equation could not be determined.
