Simplifying 5x2 + 14x + -49 = 0 Reorder the terms: -49 + 14x + 5x2 = 0 Solving -49 + 14x + 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'. -9.8 + 2.8x + x2 = 0 Move the constant term to the right: Add '9.8' to each side of the equation. -9.8 + 2.8x + 9.8 + x2 = 0 + 9.8 Reorder the terms: -9.8 + 9.8 + 2.8x + x2 = 0 + 9.8 Combine like terms: -9.8 + 9.8 = 0.0 0.0 + 2.8x + x2 = 0 + 9.8 2.8x + x2 = 0 + 9.8 Combine like terms: 0 + 9.8 = 9.8 2.8x + x2 = 9.8 The x term is 2.8x. Take half its coefficient (1.4). Square it (1.96) and add it to both sides. Add '1.96' to each side of the equation. 2.8x + 1.96 + x2 = 9.8 + 1.96 Reorder the terms: 1.96 + 2.8x + x2 = 9.8 + 1.96 Combine like terms: 9.8 + 1.96 = 11.76 1.96 + 2.8x + x2 = 11.76 Factor a perfect square on the left side: (x + 1.4)(x + 1.4) = 11.76 Calculate the square root of the right side: 3.42928564 Break this problem into two subproblems by setting (x + 1.4) equal to 3.42928564 and -3.42928564.Subproblem 1
x + 1.4 = 3.42928564 Simplifying x + 1.4 = 3.42928564 Reorder the terms: 1.4 + x = 3.42928564 Solving 1.4 + x = 3.42928564 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.4' to each side of the equation. 1.4 + -1.4 + x = 3.42928564 + -1.4 Combine like terms: 1.4 + -1.4 = 0.0 0.0 + x = 3.42928564 + -1.4 x = 3.42928564 + -1.4 Combine like terms: 3.42928564 + -1.4 = 2.02928564 x = 2.02928564 Simplifying x = 2.02928564Subproblem 2
x + 1.4 = -3.42928564 Simplifying x + 1.4 = -3.42928564 Reorder the terms: 1.4 + x = -3.42928564 Solving 1.4 + x = -3.42928564 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.4' to each side of the equation. 1.4 + -1.4 + x = -3.42928564 + -1.4 Combine like terms: 1.4 + -1.4 = 0.0 0.0 + x = -3.42928564 + -1.4 x = -3.42928564 + -1.4 Combine like terms: -3.42928564 + -1.4 = -4.82928564 x = -4.82928564 Simplifying x = -4.82928564Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.02928564, -4.82928564}
