Simplifying 79 = 3x2 + 6x Reorder the terms: 79 = 6x + 3x2 Solving 79 = 6x + 3x2 Solving for variable 'x'. Reorder the terms: 79 + -6x + -3x2 = 6x + -6x + 3x2 + -3x2 Combine like terms: 6x + -6x = 0 79 + -6x + -3x2 = 0 + 3x2 + -3x2 79 + -6x + -3x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 79 + -6x + -3x2 = 0 Begin completing the square. Divide all terms by -3 the coefficient of the squared term: Divide each side by '-3'. -26.33333333 + 2x + x2 = 0 Move the constant term to the right: Add '26.33333333' to each side of the equation. -26.33333333 + 2x + 26.33333333 + x2 = 0 + 26.33333333 Reorder the terms: -26.33333333 + 26.33333333 + 2x + x2 = 0 + 26.33333333 Combine like terms: -26.33333333 + 26.33333333 = 0.00000000 0.00000000 + 2x + x2 = 0 + 26.33333333 2x + x2 = 0 + 26.33333333 Combine like terms: 0 + 26.33333333 = 26.33333333 2x + x2 = 26.33333333 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 26.33333333 + 1 Reorder the terms: 1 + 2x + x2 = 26.33333333 + 1 Combine like terms: 26.33333333 + 1 = 27.33333333 1 + 2x + x2 = 27.33333333 Factor a perfect square on the left side: (x + 1)(x + 1) = 27.33333333 Calculate the square root of the right side: 5.228129047 Break this problem into two subproblems by setting (x + 1) equal to 5.228129047 and -5.228129047.Subproblem 1
x + 1 = 5.228129047 Simplifying x + 1 = 5.228129047 Reorder the terms: 1 + x = 5.228129047 Solving 1 + x = 5.228129047 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 5.228129047 + -1 Combine like terms: 1 + -1 = 0 0 + x = 5.228129047 + -1 x = 5.228129047 + -1 Combine like terms: 5.228129047 + -1 = 4.228129047 x = 4.228129047 Simplifying x = 4.228129047Subproblem 2
x + 1 = -5.228129047 Simplifying x + 1 = -5.228129047 Reorder the terms: 1 + x = -5.228129047 Solving 1 + x = -5.228129047 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -5.228129047 + -1 Combine like terms: 1 + -1 = 0 0 + x = -5.228129047 + -1 x = -5.228129047 + -1 Combine like terms: -5.228129047 + -1 = -6.228129047 x = -6.228129047 Simplifying x = -6.228129047Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.228129047, -6.228129047}
