Simplifying 0.003x2 + -0.39x + 16300 = 0 Reorder the terms: 16300 + -0.39x + 0.003x2 = 0 Solving 16300 + -0.39x + 0.003x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.003 the coefficient of the squared term: Divide each side by '0.003'. 5433333.333 + -130x + x2 = 0 Move the constant term to the right: Add '-5433333.333' to each side of the equation. 5433333.333 + -130x + -5433333.333 + x2 = 0 + -5433333.333 Reorder the terms: 5433333.333 + -5433333.333 + -130x + x2 = 0 + -5433333.333 Combine like terms: 5433333.333 + -5433333.333 = 0.000 0.000 + -130x + x2 = 0 + -5433333.333 -130x + x2 = 0 + -5433333.333 Combine like terms: 0 + -5433333.333 = -5433333.333 -130x + x2 = -5433333.333 The x term is -130x. Take half its coefficient (-65). Square it (4225) and add it to both sides. Add '4225' to each side of the equation. -130x + 4225 + x2 = -5433333.333 + 4225 Reorder the terms: 4225 + -130x + x2 = -5433333.333 + 4225 Combine like terms: -5433333.333 + 4225 = -5429108.333 4225 + -130x + x2 = -5429108.333 Factor a perfect square on the left side: (x + -65)(x + -65) = -5429108.333 Can't calculate square root of the right side. The solution to this equation could not be determined.
