Simplifying 5x2 + 13x + -1 = 0 Reorder the terms: -1 + 13x + 5x2 = 0 Solving -1 + 13x + 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'. -0.2 + 2.6x + x2 = 0 Move the constant term to the right: Add '0.2' to each side of the equation. -0.2 + 2.6x + 0.2 + x2 = 0 + 0.2 Reorder the terms: -0.2 + 0.2 + 2.6x + x2 = 0 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + 2.6x + x2 = 0 + 0.2 2.6x + x2 = 0 + 0.2 Combine like terms: 0 + 0.2 = 0.2 2.6x + x2 = 0.2 The x term is 2.6x. Take half its coefficient (1.3). Square it (1.69) and add it to both sides. Add '1.69' to each side of the equation. 2.6x + 1.69 + x2 = 0.2 + 1.69 Reorder the terms: 1.69 + 2.6x + x2 = 0.2 + 1.69 Combine like terms: 0.2 + 1.69 = 1.89 1.69 + 2.6x + x2 = 1.89 Factor a perfect square on the left side: (x + 1.3)(x + 1.3) = 1.89 Calculate the square root of the right side: 1.374772708 Break this problem into two subproblems by setting (x + 1.3) equal to 1.374772708 and -1.374772708.Subproblem 1
x + 1.3 = 1.374772708 Simplifying x + 1.3 = 1.374772708 Reorder the terms: 1.3 + x = 1.374772708 Solving 1.3 + x = 1.374772708 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.3' to each side of the equation. 1.3 + -1.3 + x = 1.374772708 + -1.3 Combine like terms: 1.3 + -1.3 = 0.0 0.0 + x = 1.374772708 + -1.3 x = 1.374772708 + -1.3 Combine like terms: 1.374772708 + -1.3 = 0.074772708 x = 0.074772708 Simplifying x = 0.074772708Subproblem 2
x + 1.3 = -1.374772708 Simplifying x + 1.3 = -1.374772708 Reorder the terms: 1.3 + x = -1.374772708 Solving 1.3 + x = -1.374772708 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.3' to each side of the equation. 1.3 + -1.3 + x = -1.374772708 + -1.3 Combine like terms: 1.3 + -1.3 = 0.0 0.0 + x = -1.374772708 + -1.3 x = -1.374772708 + -1.3 Combine like terms: -1.374772708 + -1.3 = -2.674772708 x = -2.674772708 Simplifying x = -2.674772708Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.074772708, -2.674772708}
