Simplifying 2n2 + -3n + 7 = 0 Reorder the terms: 7 + -3n + 2n2 = 0 Solving 7 + -3n + 2n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 3.5 + -1.5n + n2 = 0 Move the constant term to the right: Add '-3.5' to each side of the equation. 3.5 + -1.5n + -3.5 + n2 = 0 + -3.5 Reorder the terms: 3.5 + -3.5 + -1.5n + n2 = 0 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + -1.5n + n2 = 0 + -3.5 -1.5n + n2 = 0 + -3.5 Combine like terms: 0 + -3.5 = -3.5 -1.5n + n2 = -3.5 The n term is -1.5n. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5n + 0.5625 + n2 = -3.5 + 0.5625 Reorder the terms: 0.5625 + -1.5n + n2 = -3.5 + 0.5625 Combine like terms: -3.5 + 0.5625 = -2.9375 0.5625 + -1.5n + n2 = -2.9375 Factor a perfect square on the left side: (n + -0.75)(n + -0.75) = -2.9375 Can't calculate square root of the right side. The solution to this equation could not be determined.
