Simplifying 3x + x2 = -29.5 Solving 3x + x2 = -29.5 Solving for variable 'x'. Reorder the terms: 29.5 + 3x + x2 = -29.5 + 29.5 Combine like terms: -29.5 + 29.5 = 0.0 29.5 + 3x + x2 = 0.0 Begin completing the square. Move the constant term to the right: Add '-29.5' to each side of the equation. 29.5 + 3x + -29.5 + x2 = 0.0 + -29.5 Reorder the terms: 29.5 + -29.5 + 3x + x2 = 0.0 + -29.5 Combine like terms: 29.5 + -29.5 = 0.0 0.0 + 3x + x2 = 0.0 + -29.5 3x + x2 = 0.0 + -29.5 Combine like terms: 0.0 + -29.5 = -29.5 3x + x2 = -29.5 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = -29.5 + 2.25 Reorder the terms: 2.25 + 3x + x2 = -29.5 + 2.25 Combine like terms: -29.5 + 2.25 = -27.25 2.25 + 3x + x2 = -27.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = -27.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
