Simplifying 25x2 + 110x + -278 = 0 Reorder the terms: -278 + 110x + 25x2 = 0 Solving -278 + 110x + 25x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. -11.12 + 4.4x + x2 = 0 Move the constant term to the right: Add '11.12' to each side of the equation. -11.12 + 4.4x + 11.12 + x2 = 0 + 11.12 Reorder the terms: -11.12 + 11.12 + 4.4x + x2 = 0 + 11.12 Combine like terms: -11.12 + 11.12 = 0.00 0.00 + 4.4x + x2 = 0 + 11.12 4.4x + x2 = 0 + 11.12 Combine like terms: 0 + 11.12 = 11.12 4.4x + x2 = 11.12 The x term is 4.4x. Take half its coefficient (2.2). Square it (4.84) and add it to both sides. Add '4.84' to each side of the equation. 4.4x + 4.84 + x2 = 11.12 + 4.84 Reorder the terms: 4.84 + 4.4x + x2 = 11.12 + 4.84 Combine like terms: 11.12 + 4.84 = 15.96 4.84 + 4.4x + x2 = 15.96 Factor a perfect square on the left side: (x + 2.2)(x + 2.2) = 15.96 Calculate the square root of the right side: 3.994996871 Break this problem into two subproblems by setting (x + 2.2) equal to 3.994996871 and -3.994996871.Subproblem 1
x + 2.2 = 3.994996871 Simplifying x + 2.2 = 3.994996871 Reorder the terms: 2.2 + x = 3.994996871 Solving 2.2 + x = 3.994996871 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.2' to each side of the equation. 2.2 + -2.2 + x = 3.994996871 + -2.2 Combine like terms: 2.2 + -2.2 = 0.0 0.0 + x = 3.994996871 + -2.2 x = 3.994996871 + -2.2 Combine like terms: 3.994996871 + -2.2 = 1.794996871 x = 1.794996871 Simplifying x = 1.794996871Subproblem 2
x + 2.2 = -3.994996871 Simplifying x + 2.2 = -3.994996871 Reorder the terms: 2.2 + x = -3.994996871 Solving 2.2 + x = -3.994996871 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.2' to each side of the equation. 2.2 + -2.2 + x = -3.994996871 + -2.2 Combine like terms: 2.2 + -2.2 = 0.0 0.0 + x = -3.994996871 + -2.2 x = -3.994996871 + -2.2 Combine like terms: -3.994996871 + -2.2 = -6.194996871 x = -6.194996871 Simplifying x = -6.194996871Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.794996871, -6.194996871}
