Simplifying 20x + -1x2 = 120 Solving 20x + -1x2 = 120 Solving for variable 'x'. Reorder the terms: -120 + 20x + -1x2 = 120 + -120 Combine like terms: 120 + -120 = 0 -120 + 20x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 120 + -20x + x2 = 0 Move the constant term to the right: Add '-120' to each side of the equation. 120 + -20x + -120 + x2 = 0 + -120 Reorder the terms: 120 + -120 + -20x + x2 = 0 + -120 Combine like terms: 120 + -120 = 0 0 + -20x + x2 = 0 + -120 -20x + x2 = 0 + -120 Combine like terms: 0 + -120 = -120 -20x + x2 = -120 The x term is -20x. Take half its coefficient (-10). Square it (100) and add it to both sides. Add '100' to each side of the equation. -20x + 100 + x2 = -120 + 100 Reorder the terms: 100 + -20x + x2 = -120 + 100 Combine like terms: -120 + 100 = -20 100 + -20x + x2 = -20 Factor a perfect square on the left side: (x + -10)(x + -10) = -20 Can't calculate square root of the right side. The solution to this equation could not be determined.
