Simplifying (4n + 2) + (2n + -3)(3n + -2) = 0 Reorder the terms: (2 + 4n) + (2n + -3)(3n + -2) = 0 Remove parenthesis around (2 + 4n) 2 + 4n + (2n + -3)(3n + -2) = 0 Reorder the terms: 2 + 4n + (-3 + 2n)(3n + -2) = 0 Reorder the terms: 2 + 4n + (-3 + 2n)(-2 + 3n) = 0 Multiply (-3 + 2n) * (-2 + 3n) 2 + 4n + (-3(-2 + 3n) + 2n * (-2 + 3n)) = 0 2 + 4n + ((-2 * -3 + 3n * -3) + 2n * (-2 + 3n)) = 0 2 + 4n + ((6 + -9n) + 2n * (-2 + 3n)) = 0 2 + 4n + (6 + -9n + (-2 * 2n + 3n * 2n)) = 0 2 + 4n + (6 + -9n + (-4n + 6n2)) = 0 Combine like terms: -9n + -4n = -13n 2 + 4n + (6 + -13n + 6n2) = 0 Reorder the terms: 2 + 6 + 4n + -13n + 6n2 = 0 Combine like terms: 2 + 6 = 8 8 + 4n + -13n + 6n2 = 0 Combine like terms: 4n + -13n = -9n 8 + -9n + 6n2 = 0 Solving 8 + -9n + 6n2 = 0 Solving for variable 'n'. Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. 1.333333333 + -1.5n + n2 = 0 Move the constant term to the right: Add '-1.333333333' to each side of the equation. 1.333333333 + -1.5n + -1.333333333 + n2 = 0 + -1.333333333 Reorder the terms: 1.333333333 + -1.333333333 + -1.5n + n2 = 0 + -1.333333333 Combine like terms: 1.333333333 + -1.333333333 = 0.000000000 0.000000000 + -1.5n + n2 = 0 + -1.333333333 -1.5n + n2 = 0 + -1.333333333 Combine like terms: 0 + -1.333333333 = -1.333333333 -1.5n + n2 = -1.333333333 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 = -1.333333333 + 0.5625 Reorder the terms: 0.5625 + -1.5n + n2 = -1.333333333 + 0.5625 Combine like terms: -1.333333333 + 0.5625 = -0.770833333 0.5625 + -1.5n + n2 = -0.770833333 Factor a perfect square on the left side: (n + -0.75)(n + -0.75) = -0.770833333 Can't calculate square root of the right side. The solution to this equation could not be determined.
