Simplifying 2x(x + -3) + 5 = 0 Reorder the terms: 2x(-3 + x) + 5 = 0 (-3 * 2x + x * 2x) + 5 = 0 (-6x + 2x2) + 5 = 0 Reorder the terms: 5 + -6x + 2x2 = 0 Solving 5 + -6x + 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 + -3x + x2 = 0 Move the constant term to the right: Add '-2.5' to each side of the equation. 2.5 + -3x + -2.5 + x2 = 0 + -2.5 Reorder the terms: 2.5 + -2.5 + -3x + x2 = 0 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + -3x + x2 = 0 + -2.5 -3x + x2 = 0 + -2.5 Combine like terms: 0 + -2.5 = -2.5 -3x + x2 = -2.5 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 = -2.5 + 2.25 Reorder the terms: 2.25 + -3x + x2 = -2.5 + 2.25 Combine like terms: -2.5 + 2.25 = -0.25 2.25 + -3x + x2 = -0.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = -0.25 Can't calculate square root of the right side. The solution to this equation could not be determined.
