Simplifying (x + -1)(x + -1) = -7 Reorder the terms: (-1 + x)(x + -1) = -7 Reorder the terms: (-1 + x)(-1 + x) = -7 Multiply (-1 + x) * (-1 + x) (-1(-1 + x) + x(-1 + x)) = -7 ((-1 * -1 + x * -1) + x(-1 + x)) = -7 ((1 + -1x) + x(-1 + x)) = -7 (1 + -1x + (-1 * x + x * x)) = -7 (1 + -1x + (-1x + x2)) = -7 Combine like terms: -1x + -1x = -2x (1 + -2x + x2) = -7 Solving 1 + -2x + x2 = -7 Solving for variable 'x'. Reorder the terms: 1 + 7 + -2x + x2 = -7 + 7 Combine like terms: 1 + 7 = 8 8 + -2x + x2 = -7 + 7 Combine like terms: -7 + 7 = 0 8 + -2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-8' to each side of the equation. 8 + -2x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + -2x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -2x + x2 = 0 + -8 -2x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 -2x + x2 = -8 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 = -8 + 1 Reorder the terms: 1 + -2x + x2 = -8 + 1 Combine like terms: -8 + 1 = -7 1 + -2x + x2 = -7 Factor a perfect square on the left side: (x + -1)(x + -1) = -7 Can't calculate square root of the right side. The solution to this equation could not be determined.
