Simplifying (2x + -3) * 2 = 3x + -2(x + -2x) * x Reorder the terms: (-3 + 2x) * 2 = 3x + -2(x + -2x) * x Reorder the terms for easier multiplication: 2(-3 + 2x) = 3x + -2(x + -2x) * x (-3 * 2 + 2x * 2) = 3x + -2(x + -2x) * x (-6 + 4x) = 3x + -2(x + -2x) * x Combine like terms: x + -2x = -1x -6 + 4x = 3x + -2(-1x) * x Remove parenthesis around (-1x) -6 + 4x = 3x + -2 * -1x * x Multiply -2 * -1 -6 + 4x = 3x + 2x * x Multiply x * x -6 + 4x = 3x + 2x2 Solving -6 + 4x = 3x + 2x2 Solving for variable 'x'. Combine like terms: 4x + -3x = 1x -6 + 1x + -2x2 = 3x + 2x2 + -3x + -2x2 Reorder the terms: -6 + 1x + -2x2 = 3x + -3x + 2x2 + -2x2 Combine like terms: 3x + -3x = 0 -6 + 1x + -2x2 = 0 + 2x2 + -2x2 -6 + 1x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 -6 + 1x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. 3 + -0.5x + x2 = 0 Move the constant term to the right: Add '-3' to each side of the equation. 3 + -0.5x + -3 + x2 = 0 + -3 Reorder the terms: 3 + -3 + -0.5x + x2 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -0.5x + x2 = 0 + -3 -0.5x + x2 = 0 + -3 Combine like terms: 0 + -3 = -3 -0.5x + x2 = -3 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = -3 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = -3 + 0.0625 Combine like terms: -3 + 0.0625 = -2.9375 0.0625 + -0.5x + x2 = -2.9375 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = -2.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
