Simplifying 6n2 = 7n + -3 Reorder the terms: 6n2 = -3 + 7n Solving 6n2 = -3 + 7n Solving for variable 'n'. Reorder the terms: 3 + -7n + 6n2 = -3 + 7n + 3 + -7n Reorder the terms: 3 + -7n + 6n2 = -3 + 3 + 7n + -7n Combine like terms: -3 + 3 = 0 3 + -7n + 6n2 = 0 + 7n + -7n 3 + -7n + 6n2 = 7n + -7n Combine like terms: 7n + -7n = 0 3 + -7n + 6n2 = 0 Begin completing the square. Divide all terms by 6 the coefficient of the squared term: Divide each side by '6'. 0.5 + -1.166666667n + n2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -1.166666667n + -0.5 + n2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -1.166666667n + n2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -1.166666667n + n2 = 0 + -0.5 -1.166666667n + n2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -1.166666667n + n2 = -0.5 The n term is -1.166666667n. Take half its coefficient (-0.5833333335). Square it (0.3402777780) and add it to both sides. Add '0.3402777780' to each side of the equation. -1.166666667n + 0.3402777780 + n2 = -0.5 + 0.3402777780 Reorder the terms: 0.3402777780 + -1.166666667n + n2 = -0.5 + 0.3402777780 Combine like terms: -0.5 + 0.3402777780 = -0.159722222 0.3402777780 + -1.166666667n + n2 = -0.159722222 Factor a perfect square on the left side: (n + -0.5833333335)(n + -0.5833333335) = -0.159722222 Can't calculate square root of the right side. The solution to this equation could not be determined.
