Simplifying x2 + 2.33x + 1.36 = 0 Reorder the terms: 1.36 + 2.33x + x2 = 0 Solving 1.36 + 2.33x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-1.36' to each side of the equation. 1.36 + 2.33x + -1.36 + x2 = 0 + -1.36 Reorder the terms: 1.36 + -1.36 + 2.33x + x2 = 0 + -1.36 Combine like terms: 1.36 + -1.36 = 0.00 0.00 + 2.33x + x2 = 0 + -1.36 2.33x + x2 = 0 + -1.36 Combine like terms: 0 + -1.36 = -1.36 2.33x + x2 = -1.36 The x term is 2.33x. Take half its coefficient (1.165). Square it (1.357225) and add it to both sides. Add '1.357225' to each side of the equation. 2.33x + 1.357225 + x2 = -1.36 + 1.357225 Reorder the terms: 1.357225 + 2.33x + x2 = -1.36 + 1.357225 Combine like terms: -1.36 + 1.357225 = -0.002775 1.357225 + 2.33x + x2 = -0.002775 Factor a perfect square on the left side: (x + 1.165)(x + 1.165) = -0.002775 Can't calculate square root of the right side. The solution to this equation could not be determined.
