Simplifying x2 + -1.8x + 36 = 0 Reorder the terms: 36 + -1.8x + x2 = 0 Solving 36 + -1.8x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-36' to each side of the equation. 36 + -1.8x + -36 + x2 = 0 + -36 Reorder the terms: 36 + -36 + -1.8x + x2 = 0 + -36 Combine like terms: 36 + -36 = 0 0 + -1.8x + x2 = 0 + -36 -1.8x + x2 = 0 + -36 Combine like terms: 0 + -36 = -36 -1.8x + x2 = -36 The x term is -1.8x. Take half its coefficient (-0.9). Square it (0.81) and add it to both sides. Add '0.81' to each side of the equation. -1.8x + 0.81 + x2 = -36 + 0.81 Reorder the terms: 0.81 + -1.8x + x2 = -36 + 0.81 Combine like terms: -36 + 0.81 = -35.19 0.81 + -1.8x + x2 = -35.19 Factor a perfect square on the left side: (x + -0.9)(x + -0.9) = -35.19 Can't calculate square root of the right side. The solution to this equation could not be determined.
