Simplifying 5x2 + 16x + -46 = 0 Reorder the terms: -46 + 16x + 5x2 = 0 Solving -46 + 16x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -9.2 + 3.2x + x2 = 0 Move the constant term to the right: Add '9.2' to each side of the equation. -9.2 + 3.2x + 9.2 + x2 = 0 + 9.2 Reorder the terms: -9.2 + 9.2 + 3.2x + x2 = 0 + 9.2 Combine like terms: -9.2 + 9.2 = 0.0 0.0 + 3.2x + x2 = 0 + 9.2 3.2x + x2 = 0 + 9.2 Combine like terms: 0 + 9.2 = 9.2 3.2x + x2 = 9.2 The x term is 3.2x. Take half its coefficient (1.6). Square it (2.56) and add it to both sides. Add '2.56' to each side of the equation. 3.2x + 2.56 + x2 = 9.2 + 2.56 Reorder the terms: 2.56 + 3.2x + x2 = 9.2 + 2.56 Combine like terms: 9.2 + 2.56 = 11.76 2.56 + 3.2x + x2 = 11.76 Factor a perfect square on the left side: (x + 1.6)(x + 1.6) = 11.76 Calculate the square root of the right side: 3.42928564 Break this problem into two subproblems by setting (x + 1.6) equal to 3.42928564 and -3.42928564.Subproblem 1
x + 1.6 = 3.42928564 Simplifying x + 1.6 = 3.42928564 Reorder the terms: 1.6 + x = 3.42928564 Solving 1.6 + x = 3.42928564 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.6' to each side of the equation. 1.6 + -1.6 + x = 3.42928564 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + x = 3.42928564 + -1.6 x = 3.42928564 + -1.6 Combine like terms: 3.42928564 + -1.6 = 1.82928564 x = 1.82928564 Simplifying x = 1.82928564Subproblem 2
x + 1.6 = -3.42928564 Simplifying x + 1.6 = -3.42928564 Reorder the terms: 1.6 + x = -3.42928564 Solving 1.6 + x = -3.42928564 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.6' to each side of the equation. 1.6 + -1.6 + x = -3.42928564 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + x = -3.42928564 + -1.6 x = -3.42928564 + -1.6 Combine like terms: -3.42928564 + -1.6 = -5.02928564 x = -5.02928564 Simplifying x = -5.02928564Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.82928564, -5.02928564}
