Simplifying 4n2 = 7n + -2 Reorder the terms: 4n2 = -2 + 7n Solving 4n2 = -2 + 7n Solving for variable 'n'. Reorder the terms: 2 + -7n + 4n2 = -2 + 7n + 2 + -7n Reorder the terms: 2 + -7n + 4n2 = -2 + 2 + 7n + -7n Combine like terms: -2 + 2 = 0 2 + -7n + 4n2 = 0 + 7n + -7n 2 + -7n + 4n2 = 7n + -7n Combine like terms: 7n + -7n = 0 2 + -7n + 4n2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 0.5 + -1.75n + n2 = 0 Move the constant term to the right: Add '-0.5' to each side of the equation. 0.5 + -1.75n + -0.5 + n2 = 0 + -0.5 Reorder the terms: 0.5 + -0.5 + -1.75n + n2 = 0 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + -1.75n + n2 = 0 + -0.5 -1.75n + n2 = 0 + -0.5 Combine like terms: 0 + -0.5 = -0.5 -1.75n + n2 = -0.5 The n term is -1.75n. Take half its coefficient (-0.875). Square it (0.765625) and add it to both sides. Add '0.765625' to each side of the equation. -1.75n + 0.765625 + n2 = -0.5 + 0.765625 Reorder the terms: 0.765625 + -1.75n + n2 = -0.5 + 0.765625 Combine like terms: -0.5 + 0.765625 = 0.265625 0.765625 + -1.75n + n2 = 0.265625 Factor a perfect square on the left side: (n + -0.875)(n + -0.875) = 0.265625 Calculate the square root of the right side: 0.515388203 Break this problem into two subproblems by setting (n + -0.875) equal to 0.515388203 and -0.515388203.Subproblem 1
n + -0.875 = 0.515388203 Simplifying n + -0.875 = 0.515388203 Reorder the terms: -0.875 + n = 0.515388203 Solving -0.875 + n = 0.515388203 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.875' to each side of the equation. -0.875 + 0.875 + n = 0.515388203 + 0.875 Combine like terms: -0.875 + 0.875 = 0.000 0.000 + n = 0.515388203 + 0.875 n = 0.515388203 + 0.875 Combine like terms: 0.515388203 + 0.875 = 1.390388203 n = 1.390388203 Simplifying n = 1.390388203Subproblem 2
n + -0.875 = -0.515388203 Simplifying n + -0.875 = -0.515388203 Reorder the terms: -0.875 + n = -0.515388203 Solving -0.875 + n = -0.515388203 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '0.875' to each side of the equation. -0.875 + 0.875 + n = -0.515388203 + 0.875 Combine like terms: -0.875 + 0.875 = 0.000 0.000 + n = -0.515388203 + 0.875 n = -0.515388203 + 0.875 Combine like terms: -0.515388203 + 0.875 = 0.359611797 n = 0.359611797 Simplifying n = 0.359611797Solution
