Simplifying 4 + -3n + 10n2 = 0 Solving 4 + -3n + 10n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 0.4 + -0.3n + n2 = 0 Move the constant term to the right: Add '-0.4' to each side of the equation. 0.4 + -0.3n + -0.4 + n2 = 0 + -0.4 Reorder the terms: 0.4 + -0.4 + -0.3n + n2 = 0 + -0.4 Combine like terms: 0.4 + -0.4 = 0.0 0.0 + -0.3n + n2 = 0 + -0.4 -0.3n + n2 = 0 + -0.4 Combine like terms: 0 + -0.4 = -0.4 -0.3n + n2 = -0.4 The n term is -0.3n. Take half its coefficient (-0.15). Square it (0.0225) and add it to both sides. Add '0.0225' to each side of the equation. -0.3n + 0.0225 + n2 = -0.4 + 0.0225 Reorder the terms: 0.0225 + -0.3n + n2 = -0.4 + 0.0225 Combine like terms: -0.4 + 0.0225 = -0.3775 0.0225 + -0.3n + n2 = -0.3775 Factor a perfect square on the left side: (n + -0.15)(n + -0.15) = -0.3775 Can't calculate square root of the right side. The solution to this equation could not be determined.
