Simplifying 6.59 = x2 + 3x + 1 Reorder the terms: 6.59 = 1 + 3x + x2 Solving 6.59 = 1 + 3x + x2 Solving for variable 'x'. Combine like terms: 6.59 + -1 = 5.59 5.59 + -3x + -1x2 = 1 + 3x + x2 + -1 + -3x + -1x2 Reorder the terms: 5.59 + -3x + -1x2 = 1 + -1 + 3x + -3x + x2 + -1x2 Combine like terms: 1 + -1 = 0 5.59 + -3x + -1x2 = 0 + 3x + -3x + x2 + -1x2 5.59 + -3x + -1x2 = 3x + -3x + x2 + -1x2 Combine like terms: 3x + -3x = 0 5.59 + -3x + -1x2 = 0 + x2 + -1x2 5.59 + -3x + -1x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 5.59 + -3x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -5.59 + 3x + x2 = 0 Move the constant term to the right: Add '5.59' to each side of the equation. -5.59 + 3x + 5.59 + x2 = 0 + 5.59 Reorder the terms: -5.59 + 5.59 + 3x + x2 = 0 + 5.59 Combine like terms: -5.59 + 5.59 = 0.00 0.00 + 3x + x2 = 0 + 5.59 3x + x2 = 0 + 5.59 Combine like terms: 0 + 5.59 = 5.59 3x + x2 = 5.59 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 5.59 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 5.59 + 2.25 Combine like terms: 5.59 + 2.25 = 7.84 2.25 + 3x + x2 = 7.84 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 7.84 Calculate the square root of the right side: 2.8 Break this problem into two subproblems by setting (x + 1.5) equal to 2.8 and -2.8.Subproblem 1
x + 1.5 = 2.8 Simplifying x + 1.5 = 2.8 Reorder the terms: 1.5 + x = 2.8 Solving 1.5 + x = 2.8 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 2.8 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 2.8 + -1.5 x = 2.8 + -1.5 Combine like terms: 2.8 + -1.5 = 1.3 x = 1.3 Simplifying x = 1.3Subproblem 2
x + 1.5 = -2.8 Simplifying x + 1.5 = -2.8 Reorder the terms: 1.5 + x = -2.8 Solving 1.5 + x = -2.8 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -2.8 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -2.8 + -1.5 x = -2.8 + -1.5 Combine like terms: -2.8 + -1.5 = -4.3 x = -4.3 Simplifying x = -4.3Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.3, -4.3}
