Simplifying 0.05x2 + 4x + 200000 = 0 Reorder the terms: 200000 + 4x + 0.05x2 = 0 Solving 200000 + 4x + 0.05x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.05 the coefficient of the squared term: Divide each side by '0.05'. 4000000 + 80x + x2 = 0 Move the constant term to the right: Add '-4000000' to each side of the equation. 4000000 + 80x + -4000000 + x2 = 0 + -4000000 Reorder the terms: 4000000 + -4000000 + 80x + x2 = 0 + -4000000 Combine like terms: 4000000 + -4000000 = 0 0 + 80x + x2 = 0 + -4000000 80x + x2 = 0 + -4000000 Combine like terms: 0 + -4000000 = -4000000 80x + x2 = -4000000 The x term is 80x. Take half its coefficient (40). Square it (1600) and add it to both sides. Add '1600' to each side of the equation. 80x + 1600 + x2 = -4000000 + 1600 Reorder the terms: 1600 + 80x + x2 = -4000000 + 1600 Combine like terms: -4000000 + 1600 = -3998400 1600 + 80x + x2 = -3998400 Factor a perfect square on the left side: (x + 40)(x + 40) = -3998400 Can't calculate square root of the right side. The solution to this equation could not be determined.
