Simplifying -4b2 + 6b + -15 = 0 Reorder the terms: -15 + 6b + -4b2 = 0 Solving -15 + 6b + -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'. 3.75 + -1.5b + b2 = 0 Move the constant term to the right: Add '-3.75' to each side of the equation. 3.75 + -1.5b + -3.75 + b2 = 0 + -3.75 Reorder the terms: 3.75 + -3.75 + -1.5b + b2 = 0 + -3.75 Combine like terms: 3.75 + -3.75 = 0.00 0.00 + -1.5b + b2 = 0 + -3.75 -1.5b + b2 = 0 + -3.75 Combine like terms: 0 + -3.75 = -3.75 -1.5b + b2 = -3.75 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 = -3.75 + 0.5625 Reorder the terms: 0.5625 + -1.5b + b2 = -3.75 + 0.5625 Combine like terms: -3.75 + 0.5625 = -3.1875 0.5625 + -1.5b + b2 = -3.1875 Factor a perfect square on the left side: (b + -0.75)(b + -0.75) = -3.1875 Can't calculate square root of the right side. The solution to this equation could not be determined.
