Simplifying x2 + -3x + 3 = -7x + -3 Reorder the terms: 3 + -3x + x2 = -7x + -3 Reorder the terms: 3 + -3x + x2 = -3 + -7x Solving 3 + -3x + x2 = -3 + -7x Solving for variable 'x'. Reorder the terms: 3 + 3 + -3x + 7x + x2 = -3 + -7x + 3 + 7x Combine like terms: 3 + 3 = 6 6 + -3x + 7x + x2 = -3 + -7x + 3 + 7x Combine like terms: -3x + 7x = 4x 6 + 4x + x2 = -3 + -7x + 3 + 7x Reorder the terms: 6 + 4x + x2 = -3 + 3 + -7x + 7x Combine like terms: -3 + 3 = 0 6 + 4x + x2 = 0 + -7x + 7x 6 + 4x + x2 = -7x + 7x Combine like terms: -7x + 7x = 0 6 + 4x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-6' to each side of the equation. 6 + 4x + -6 + x2 = 0 + -6 Reorder the terms: 6 + -6 + 4x + x2 = 0 + -6 Combine like terms: 6 + -6 = 0 0 + 4x + x2 = 0 + -6 4x + x2 = 0 + -6 Combine like terms: 0 + -6 = -6 4x + x2 = -6 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = -6 + 4 Reorder the terms: 4 + 4x + x2 = -6 + 4 Combine like terms: -6 + 4 = -2 4 + 4x + x2 = -2 Factor a perfect square on the left side: (x + 2)(x + 2) = -2 Can't calculate square root of the right side. The solution to this equation could not be determined.
