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