Simplifying 15x2 + 3x + 20 = 0 Reorder the terms: 20 + 3x + 15x2 = 0 Solving 20 + 3x + 15x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 15 the coefficient of the squared term: Divide each side by '15'. 1.333333333 + 0.2x + x2 = 0 Move the constant term to the right: Add '-1.333333333' to each side of the equation. 1.333333333 + 0.2x + -1.333333333 + x2 = 0 + -1.333333333 Reorder the terms: 1.333333333 + -1.333333333 + 0.2x + x2 = 0 + -1.333333333 Combine like terms: 1.333333333 + -1.333333333 = 0.000000000 0.000000000 + 0.2x + x2 = 0 + -1.333333333 0.2x + x2 = 0 + -1.333333333 Combine like terms: 0 + -1.333333333 = -1.333333333 0.2x + x2 = -1.333333333 The x term is 0.2x. Take half its coefficient (0.1). Square it (0.01) and add it to both sides. Add '0.01' to each side of the equation. 0.2x + 0.01 + x2 = -1.333333333 + 0.01 Reorder the terms: 0.01 + 0.2x + x2 = -1.333333333 + 0.01 Combine like terms: -1.333333333 + 0.01 = -1.323333333 0.01 + 0.2x + x2 = -1.323333333 Factor a perfect square on the left side: (x + 0.1)(x + 0.1) = -1.323333333 Can't calculate square root of the right side. The solution to this equation could not be determined.
