Simplifying 4x2 + 19x + 60 = 0 Reorder the terms: 60 + 19x + 4x2 = 0 Solving 60 + 19x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 15 + 4.75x + x2 = 0 Move the constant term to the right: Add '-15' to each side of the equation. 15 + 4.75x + -15 + x2 = 0 + -15 Reorder the terms: 15 + -15 + 4.75x + x2 = 0 + -15 Combine like terms: 15 + -15 = 0 0 + 4.75x + x2 = 0 + -15 4.75x + x2 = 0 + -15 Combine like terms: 0 + -15 = -15 4.75x + x2 = -15 The x term is 4.75x. Take half its coefficient (2.375). Square it (5.640625) and add it to both sides. Add '5.640625' to each side of the equation. 4.75x + 5.640625 + x2 = -15 + 5.640625 Reorder the terms: 5.640625 + 4.75x + x2 = -15 + 5.640625 Combine like terms: -15 + 5.640625 = -9.359375 5.640625 + 4.75x + x2 = -9.359375 Factor a perfect square on the left side: (x + 2.375)(x + 2.375) = -9.359375 Can't calculate square root of the right side. The solution to this equation could not be determined.
