Simplifying 0.1x2 + -10x + 1000 = 0 Reorder the terms: 1000 + -10x + 0.1x2 = 0 Solving 1000 + -10x + 0.1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.1 the coefficient of the squared term: Divide each side by '0.1'. 10000 + -100x + x2 = 0 Move the constant term to the right: Add '-10000' to each side of the equation. 10000 + -100x + -10000 + x2 = 0 + -10000 Reorder the terms: 10000 + -10000 + -100x + x2 = 0 + -10000 Combine like terms: 10000 + -10000 = 0 0 + -100x + x2 = 0 + -10000 -100x + x2 = 0 + -10000 Combine like terms: 0 + -10000 = -10000 -100x + x2 = -10000 The x term is -100x. Take half its coefficient (-50). Square it (2500) and add it to both sides. Add '2500' to each side of the equation. -100x + 2500 + x2 = -10000 + 2500 Reorder the terms: 2500 + -100x + x2 = -10000 + 2500 Combine like terms: -10000 + 2500 = -7500 2500 + -100x + x2 = -7500 Factor a perfect square on the left side: (x + -50)(x + -50) = -7500 Can't calculate square root of the right side. The solution to this equation could not be determined.
