Simplifying x2 + -3x + 10 = 2x + -1 Reorder the terms: 10 + -3x + x2 = 2x + -1 Reorder the terms: 10 + -3x + x2 = -1 + 2x Solving 10 + -3x + x2 = -1 + 2x Solving for variable 'x'. Reorder the terms: 10 + 1 + -3x + -2x + x2 = -1 + 2x + 1 + -2x Combine like terms: 10 + 1 = 11 11 + -3x + -2x + x2 = -1 + 2x + 1 + -2x Combine like terms: -3x + -2x = -5x 11 + -5x + x2 = -1 + 2x + 1 + -2x Reorder the terms: 11 + -5x + x2 = -1 + 1 + 2x + -2x Combine like terms: -1 + 1 = 0 11 + -5x + x2 = 0 + 2x + -2x 11 + -5x + x2 = 2x + -2x Combine like terms: 2x + -2x = 0 11 + -5x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-11' to each side of the equation. 11 + -5x + -11 + x2 = 0 + -11 Reorder the terms: 11 + -11 + -5x + x2 = 0 + -11 Combine like terms: 11 + -11 = 0 0 + -5x + x2 = 0 + -11 -5x + x2 = 0 + -11 Combine like terms: 0 + -11 = -11 -5x + x2 = -11 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -11 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -11 + 6.25 Combine like terms: -11 + 6.25 = -4.75 6.25 + -5x + x2 = -4.75 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = -4.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
