Simplifying 0.7x + 2x(x + -3) = 0.2x + 3 Reorder the terms: 0.7x + 2x(-3 + x) = 0.2x + 3 0.7x + (-3 * 2x + x * 2x) = 0.2x + 3 0.7x + (-6x + 2x2) = 0.2x + 3 Combine like terms: 0.7x + -6x = -5.3x -5.3x + 2x2 = 0.2x + 3 Reorder the terms: -5.3x + 2x2 = 3 + 0.2x Solving -5.3x + 2x2 = 3 + 0.2x Solving for variable 'x'. Reorder the terms: -3 + -5.3x + -0.2x + 2x2 = 3 + 0.2x + -3 + -0.2x Combine like terms: -5.3x + -0.2x = -5.5x -3 + -5.5x + 2x2 = 3 + 0.2x + -3 + -0.2x Reorder the terms: -3 + -5.5x + 2x2 = 3 + -3 + 0.2x + -0.2x Combine like terms: 3 + -3 = 0 -3 + -5.5x + 2x2 = 0 + 0.2x + -0.2x -3 + -5.5x + 2x2 = 0.2x + -0.2x Combine like terms: 0.2x + -0.2x = 0.0 -3 + -5.5x + 2x2 = 0.0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -1.5 + -2.75x + x2 = 0.0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + -2.75x + 1.5 + x2 = 0.0 + 1.5 Reorder the terms: -1.5 + 1.5 + -2.75x + x2 = 0.0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + -2.75x + x2 = 0.0 + 1.5 -2.75x + x2 = 0.0 + 1.5 Combine like terms: 0.0 + 1.5 = 1.5 -2.75x + x2 = 1.5 The x term is -2.75x. Take half its coefficient (-1.375). Square it (1.890625) and add it to both sides. Add '1.890625' to each side of the equation. -2.75x + 1.890625 + x2 = 1.5 + 1.890625 Reorder the terms: 1.890625 + -2.75x + x2 = 1.5 + 1.890625 Combine like terms: 1.5 + 1.890625 = 3.390625 1.890625 + -2.75x + x2 = 3.390625 Factor a perfect square on the left side: (x + -1.375)(x + -1.375) = 3.390625 Calculate the square root of the right side: 1.841364983 Break this problem into two subproblems by setting (x + -1.375) equal to 1.841364983 and -1.841364983.Subproblem 1
x + -1.375 = 1.841364983 Simplifying x + -1.375 = 1.841364983 Reorder the terms: -1.375 + x = 1.841364983 Solving -1.375 + x = 1.841364983 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.375' to each side of the equation. -1.375 + 1.375 + x = 1.841364983 + 1.375 Combine like terms: -1.375 + 1.375 = 0.000 0.000 + x = 1.841364983 + 1.375 x = 1.841364983 + 1.375 Combine like terms: 1.841364983 + 1.375 = 3.216364983 x = 3.216364983 Simplifying x = 3.216364983Subproblem 2
x + -1.375 = -1.841364983 Simplifying x + -1.375 = -1.841364983 Reorder the terms: -1.375 + x = -1.841364983 Solving -1.375 + x = -1.841364983 Solving for variable 'x'.
