Simplifying 0.9x + -0.7(12 + -2) = -0.4x(x + -0.6) Combine like terms: 12 + -2 = 10 0.9x + -0.7(10) = -0.4x(x + -0.6) Multiply -0.7 * 10 0.9x + -7 = -0.4x(x + -0.6) Reorder the terms: -7 + 0.9x = -0.4x(x + -0.6) Reorder the terms: -7 + 0.9x = -0.4x(-0.6 + x) -7 + 0.9x = (-0.6 * -0.4x + x * -0.4x) -7 + 0.9x = (0.24x + -0.4x2) Solving -7 + 0.9x = 0.24x + -0.4x2 Solving for variable 'x'. Combine like terms: 0.9x + -0.24x = 0.66x -7 + 0.66x + 0.4x2 = 0.24x + -0.4x2 + -0.24x + 0.4x2 Reorder the terms: -7 + 0.66x + 0.4x2 = 0.24x + -0.24x + -0.4x2 + 0.4x2 Combine like terms: 0.24x + -0.24x = 0.00 -7 + 0.66x + 0.4x2 = 0.00 + -0.4x2 + 0.4x2 -7 + 0.66x + 0.4x2 = -0.4x2 + 0.4x2 Combine like terms: -0.4x2 + 0.4x2 = 0.0 -7 + 0.66x + 0.4x2 = 0.0 Begin completing the square. Divide all terms by 0.4 the coefficient of the squared term: Divide each side by '0.4'. -17.5 + 1.65x + x2 = 0 Move the constant term to the right: Add '17.5' to each side of the equation. -17.5 + 1.65x + 17.5 + x2 = 0 + 17.5 Reorder the terms: -17.5 + 17.5 + 1.65x + x2 = 0 + 17.5 Combine like terms: -17.5 + 17.5 = 0.0 0.0 + 1.65x + x2 = 0 + 17.5 1.65x + x2 = 0 + 17.5 Combine like terms: 0 + 17.5 = 17.5 1.65x + x2 = 17.5 The x term is 1.65x. Take half its coefficient (0.825). Square it (0.680625) and add it to both sides. Add '0.680625' to each side of the equation. 1.65x + 0.680625 + x2 = 17.5 + 0.680625 Reorder the terms: 0.680625 + 1.65x + x2 = 17.5 + 0.680625 Combine like terms: 17.5 + 0.680625 = 18.180625 0.680625 + 1.65x + x2 = 18.180625 Factor a perfect square on the left side: (x + 0.825)(x + 0.825) = 18.180625 Calculate the square root of the right side: 4.263874412 Break this problem into two subproblems by setting (x + 0.825) equal to 4.263874412 and -4.263874412.Subproblem 1
x + 0.825 = 4.263874412 Simplifying x + 0.825 = 4.263874412 Reorder the terms: 0.825 + x = 4.263874412 Solving 0.825 + x = 4.263874412 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.825' to each side of the equation. 0.825 + -0.825 + x = 4.263874412 + -0.825 Combine like terms: 0.825 + -0.825 = 0.000 0.000 + x = 4.263874412 + -0.825 x = 4.263874412 + -0.825 Combine like terms: 4.263874412 + -0.825 = 3.438874412 x = 3.438874412 Simplifying x = 3.438874412Subproblem 2
x + 0.825 = -4.263874412 Simplifying x + 0.825 = -4.263874412 Reorder the terms: 0.825 + x = -4.263874412 Solving 0.825 + x = -4.263874412 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.825' to each side of the equation. 0.825 + -0.825 + x = -4.263874412 + -0.825 Combine like terms: 0.825 + -0.825 = 0.000 0.000 + x = -4.263874412 + -0.825 x = -4.263874412 + -0.825 Combine like terms: -4.263874412 + -0.825 = -5.088874412 x = -5.088874412 Simplifying x = -5.088874412Solution
