Simplifying 3x2 + 4x = x2 + -7x + -28 Reorder the terms: 4x + 3x2 = x2 + -7x + -28 Reorder the terms: 4x + 3x2 = -28 + -7x + x2 Solving 4x + 3x2 = -28 + -7x + x2 Solving for variable 'x'. Reorder the terms: 28 + 4x + 7x + 3x2 + -1x2 = -28 + -7x + x2 + 28 + 7x + -1x2 Combine like terms: 4x + 7x = 11x 28 + 11x + 3x2 + -1x2 = -28 + -7x + x2 + 28 + 7x + -1x2 Combine like terms: 3x2 + -1x2 = 2x2 28 + 11x + 2x2 = -28 + -7x + x2 + 28 + 7x + -1x2 Reorder the terms: 28 + 11x + 2x2 = -28 + 28 + -7x + 7x + x2 + -1x2 Combine like terms: -28 + 28 = 0 28 + 11x + 2x2 = 0 + -7x + 7x + x2 + -1x2 28 + 11x + 2x2 = -7x + 7x + x2 + -1x2 Combine like terms: -7x + 7x = 0 28 + 11x + 2x2 = 0 + x2 + -1x2 28 + 11x + 2x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 28 + 11x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 14 + 5.5x + x2 = 0 Move the constant term to the right: Add '-14' to each side of the equation. 14 + 5.5x + -14 + x2 = 0 + -14 Reorder the terms: 14 + -14 + 5.5x + x2 = 0 + -14 Combine like terms: 14 + -14 = 0 0 + 5.5x + x2 = 0 + -14 5.5x + x2 = 0 + -14 Combine like terms: 0 + -14 = -14 5.5x + x2 = -14 The x term is 5.5x. Take half its coefficient (2.75). Square it (7.5625) and add it to both sides. Add '7.5625' to each side of the equation. 5.5x + 7.5625 + x2 = -14 + 7.5625 Reorder the terms: 7.5625 + 5.5x + x2 = -14 + 7.5625 Combine like terms: -14 + 7.5625 = -6.4375 7.5625 + 5.5x + x2 = -6.4375 Factor a perfect square on the left side: (x + 2.75)(x + 2.75) = -6.4375 Can't calculate square root of the right side. The solution to this equation could not be determined.
