Simplifying x2 + -1.5x + 1.44 = 0 Reorder the terms: 1.44 + -1.5x + x2 = 0 Solving 1.44 + -1.5x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-1.44' to each side of the equation. 1.44 + -1.5x + -1.44 + x2 = 0 + -1.44 Reorder the terms: 1.44 + -1.44 + -1.5x + x2 = 0 + -1.44 Combine like terms: 1.44 + -1.44 = 0.00 0.00 + -1.5x + x2 = 0 + -1.44 -1.5x + x2 = 0 + -1.44 Combine like terms: 0 + -1.44 = -1.44 -1.5x + x2 = -1.44 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = -1.44 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = -1.44 + 0.5625 Combine like terms: -1.44 + 0.5625 = -0.8775 0.5625 + -1.5x + x2 = -0.8775 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = -0.8775 Can't calculate square root of the right side. The solution to this equation could not be determined.
