Simplifying 5x2 + -10x + -126 = 0 Reorder the terms: -126 + -10x + 5x2 = 0 Solving -126 + -10x + 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'. -25.2 + -2x + x2 = 0 Move the constant term to the right: Add '25.2' to each side of the equation. -25.2 + -2x + 25.2 + x2 = 0 + 25.2 Reorder the terms: -25.2 + 25.2 + -2x + x2 = 0 + 25.2 Combine like terms: -25.2 + 25.2 = 0.0 0.0 + -2x + x2 = 0 + 25.2 -2x + x2 = 0 + 25.2 Combine like terms: 0 + 25.2 = 25.2 -2x + x2 = 25.2 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 = 25.2 + 1 Reorder the terms: 1 + -2x + x2 = 25.2 + 1 Combine like terms: 25.2 + 1 = 26.2 1 + -2x + x2 = 26.2 Factor a perfect square on the left side: (x + -1)(x + -1) = 26.2 Calculate the square root of the right side: 5.118593557 Break this problem into two subproblems by setting (x + -1) equal to 5.118593557 and -5.118593557.Subproblem 1
x + -1 = 5.118593557 Simplifying x + -1 = 5.118593557 Reorder the terms: -1 + x = 5.118593557 Solving -1 + x = 5.118593557 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 = 5.118593557 + 1 Combine like terms: -1 + 1 = 0 0 + x = 5.118593557 + 1 x = 5.118593557 + 1 Combine like terms: 5.118593557 + 1 = 6.118593557 x = 6.118593557 Simplifying x = 6.118593557Subproblem 2
x + -1 = -5.118593557 Simplifying x + -1 = -5.118593557 Reorder the terms: -1 + x = -5.118593557 Solving -1 + x = -5.118593557 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 = -5.118593557 + 1 Combine like terms: -1 + 1 = 0 0 + x = -5.118593557 + 1 x = -5.118593557 + 1 Combine like terms: -5.118593557 + 1 = -4.118593557 x = -4.118593557 Simplifying x = -4.118593557Solution
The solution to the problem is based on the solutions from the subproblems. x = {6.118593557, -4.118593557}
