Simplifying (2x + -1)(2x + -1) = -16 Reorder the terms: (-1 + 2x)(2x + -1) = -16 Reorder the terms: (-1 + 2x)(-1 + 2x) = -16 Multiply (-1 + 2x) * (-1 + 2x) (-1(-1 + 2x) + 2x * (-1 + 2x)) = -16 ((-1 * -1 + 2x * -1) + 2x * (-1 + 2x)) = -16 ((1 + -2x) + 2x * (-1 + 2x)) = -16 (1 + -2x + (-1 * 2x + 2x * 2x)) = -16 (1 + -2x + (-2x + 4x2)) = -16 Combine like terms: -2x + -2x = -4x (1 + -4x + 4x2) = -16 Solving 1 + -4x + 4x2 = -16 Solving for variable 'x'. Reorder the terms: 1 + 16 + -4x + 4x2 = -16 + 16 Combine like terms: 1 + 16 = 17 17 + -4x + 4x2 = -16 + 16 Combine like terms: -16 + 16 = 0 17 + -4x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 4.25 + -1x + x2 = 0 Move the constant term to the right: Add '-4.25' to each side of the equation. 4.25 + -1x + -4.25 + x2 = 0 + -4.25 Reorder the terms: 4.25 + -4.25 + -1x + x2 = 0 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 0.00 + -1x + x2 = 0 + -4.25 -1x + x2 = 0 + -4.25 Combine like terms: 0 + -4.25 = -4.25 -1x + x2 = -4.25 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = -4.25 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -4.25 + 0.25 Combine like terms: -4.25 + 0.25 = -4 0.25 + -1x + x2 = -4 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = -4 Can't calculate square root of the right side. The solution to this equation could not be determined.
