Simplifying 0.5x(x + -1.2) = x + -0.8 Reorder the terms: 0.5x(-1.2 + x) = x + -0.8 (-1.2 * 0.5x + x * 0.5x) = x + -0.8 (-0.6x + 0.5x2) = x + -0.8 Reorder the terms: -0.6x + 0.5x2 = -0.8 + x Solving -0.6x + 0.5x2 = -0.8 + x Solving for variable 'x'. Reorder the terms: 0.8 + -0.6x + -1x + 0.5x2 = -0.8 + x + 0.8 + -1x Combine like terms: -0.6x + -1x = -1.6x 0.8 + -1.6x + 0.5x2 = -0.8 + x + 0.8 + -1x Reorder the terms: 0.8 + -1.6x + 0.5x2 = -0.8 + 0.8 + x + -1x Combine like terms: -0.8 + 0.8 = 0.0 0.8 + -1.6x + 0.5x2 = 0.0 + x + -1x 0.8 + -1.6x + 0.5x2 = x + -1x Combine like terms: x + -1x = 0 0.8 + -1.6x + 0.5x2 = 0 Begin completing the square. Divide all terms by 0.5 the coefficient of the squared term: Divide each side by '0.5'. 1.6 + -3.2x + x2 = 0 Move the constant term to the right: Add '-1.6' to each side of the equation. 1.6 + -3.2x + -1.6 + x2 = 0 + -1.6 Reorder the terms: 1.6 + -1.6 + -3.2x + x2 = 0 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + -3.2x + x2 = 0 + -1.6 -3.2x + x2 = 0 + -1.6 Combine like terms: 0 + -1.6 = -1.6 -3.2x + x2 = -1.6 The x term is -3.2x. Take half its coefficient (-1.6). Square it (2.56) and add it to both sides. Add '2.56' to each side of the equation. -3.2x + 2.56 + x2 = -1.6 + 2.56 Reorder the terms: 2.56 + -3.2x + x2 = -1.6 + 2.56 Combine like terms: -1.6 + 2.56 = 0.96 2.56 + -3.2x + x2 = 0.96 Factor a perfect square on the left side: (x + -1.6)(x + -1.6) = 0.96 Calculate the square root of the right side: 0.979795897 Break this problem into two subproblems by setting (x + -1.6) equal to 0.979795897 and -0.979795897.Subproblem 1
x + -1.6 = 0.979795897 Simplifying x + -1.6 = 0.979795897 Reorder the terms: -1.6 + x = 0.979795897 Solving -1.6 + x = 0.979795897 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.6' to each side of the equation. -1.6 + 1.6 + x = 0.979795897 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + x = 0.979795897 + 1.6 x = 0.979795897 + 1.6 Combine like terms: 0.979795897 + 1.6 = 2.579795897 x = 2.579795897 Simplifying x = 2.579795897Subproblem 2
x + -1.6 = -0.979795897 Simplifying x + -1.6 = -0.979795897 Reorder the terms: -1.6 + x = -0.979795897 Solving -1.6 + x = -0.979795897 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.6' to each side of the equation. -1.6 + 1.6 + x = -0.979795897 + 1.6 Combine like terms: -1.6 + 1.6 = 0.0 0.0 + x = -0.979795897 + 1.6 x = -0.979795897 + 1.6 Combine like terms: -0.979795897 + 1.6 = 0.620204103 x = 0.620204103 Simplifying x = 0.620204103Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.579795897, 0.620204103}
