Simplifying 0.5 * 4x2 + 4x + 5 = 0 Multiply 0.5 * 4 2x2 + 4x + 5 = 0 Reorder the terms: 5 + 4x + 2x2 = 0 Solving 5 + 4x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 2.5 + 2x + x2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + 2x + -2.5 + x2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + 2x + x2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + 2x + x2 = 0 + -2.5 2x + x2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 2x + x2 = -2.5 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = -2.5 + 1 Reorder the terms: 1 + 2x + x2 = -2.5 + 1 Combine like terms: -2.5 + 1 = -1.5 1 + 2x + x2 = -1.5 Factor a perfect square on the left side: (x + 1)(x + 1) = -1.5 Can't calculate square root of the right side. The solution to this equation could not be determined.
