Simplifying 0 = -4x2 + 2x + -7 Reorder the terms: 0 = -7 + 2x + -4x2 Solving 0 = -7 + 2x + -4x2 Solving for variable 'x'. Combine like terms: 0 + 7 = 7 7 + -2x + 4x2 = -7 + 2x + -4x2 + 7 + -2x + 4x2 Reorder the terms: 7 + -2x + 4x2 = -7 + 7 + 2x + -2x + -4x2 + 4x2 Combine like terms: -7 + 7 = 0 7 + -2x + 4x2 = 0 + 2x + -2x + -4x2 + 4x2 7 + -2x + 4x2 = 2x + -2x + -4x2 + 4x2 Combine like terms: 2x + -2x = 0 7 + -2x + 4x2 = 0 + -4x2 + 4x2 7 + -2x + 4x2 = -4x2 + 4x2 Combine like terms: -4x2 + 4x2 = 0 7 + -2x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 1.75 + -0.5x + x2 = 0 Move the constant term to the right: Add '-1.75' to each side of the equation. 1.75 + -0.5x + -1.75 + x2 = 0 + -1.75 Reorder the terms: 1.75 + -1.75 + -0.5x + x2 = 0 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + -0.5x + x2 = 0 + -1.75 -0.5x + x2 = 0 + -1.75 Combine like terms: 0 + -1.75 = -1.75 -0.5x + x2 = -1.75 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 = -1.75 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = -1.75 + 0.0625 Combine like terms: -1.75 + 0.0625 = -1.6875 0.0625 + -0.5x + x2 = -1.6875 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = -1.6875 Can't calculate square root of the right side. The solution to this equation could not be determined.
