Simplifying 0.5x + -0.1x(18 + -5x) = -0.3(x + -7) 0.5x + (18 * -0.1x + -5x * -0.1x) = -0.3(x + -7) 0.5x + (-1.8x + 0.5x2) = -0.3(x + -7) Combine like terms: 0.5x + -1.8x = -1.3x -1.3x + 0.5x2 = -0.3(x + -7) Reorder the terms: -1.3x + 0.5x2 = -0.3(-7 + x) -1.3x + 0.5x2 = (-7 * -0.3 + x * -0.3) -1.3x + 0.5x2 = (2.1 + -0.3x) Solving -1.3x + 0.5x2 = 2.1 + -0.3x Solving for variable 'x'. Reorder the terms: -2.1 + -1.3x + 0.3x + 0.5x2 = 2.1 + -0.3x + -2.1 + 0.3x Combine like terms: -1.3x + 0.3x = -1x -2.1 + -1x + 0.5x2 = 2.1 + -0.3x + -2.1 + 0.3x Reorder the terms: -2.1 + -1x + 0.5x2 = 2.1 + -2.1 + -0.3x + 0.3x Combine like terms: 2.1 + -2.1 = 0.0 -2.1 + -1x + 0.5x2 = 0.0 + -0.3x + 0.3x -2.1 + -1x + 0.5x2 = -0.3x + 0.3x Combine like terms: -0.3x + 0.3x = 0.0 -2.1 + -1x + 0.5x2 = 0.0 Begin completing the square. Divide all terms by 0.5 the coefficient of the squared term: Divide each side by '0.5'. -4.2 + -2x + x2 = 0 Move the constant term to the right: Add '4.2' to each side of the equation. -4.2 + -2x + 4.2 + x2 = 0 + 4.2 Reorder the terms: -4.2 + 4.2 + -2x + x2 = 0 + 4.2 Combine like terms: -4.2 + 4.2 = 0.0 0.0 + -2x + x2 = 0 + 4.2 -2x + x2 = 0 + 4.2 Combine like terms: 0 + 4.2 = 4.2 -2x + x2 = 4.2 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 = 4.2 + 1 Reorder the terms: 1 + -2x + x2 = 4.2 + 1 Combine like terms: 4.2 + 1 = 5.2 1 + -2x + x2 = 5.2 Factor a perfect square on the left side: (x + -1)(x + -1) = 5.2 Calculate the square root of the right side: 2.28035085 Break this problem into two subproblems by setting (x + -1) equal to 2.28035085 and -2.28035085.Subproblem 1
x + -1 = 2.28035085 Simplifying x + -1 = 2.28035085 Reorder the terms: -1 + x = 2.28035085 Solving -1 + x = 2.28035085 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 = 2.28035085 + 1 Combine like terms: -1 + 1 = 0 0 + x = 2.28035085 + 1 x = 2.28035085 + 1 Combine like terms: 2.28035085 + 1 = 3.28035085 x = 3.28035085 Simplifying x = 3.28035085Subproblem 2
x + -1 = -2.28035085 Simplifying x + -1 = -2.28035085 Reorder the terms: -1 + x = -2.28035085 Solving -1 + x = -2.28035085 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 = -2.28035085 + 1 Combine like terms: -1 + 1 = 0 0 + x = -2.28035085 + 1 x = -2.28035085 + 1 Combine like terms: -2.28035085 + 1 = -1.28035085 x = -1.28035085 Simplifying x = -1.28035085Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.28035085, -1.28035085}
