Simplifying 18 + 5x2 = 20x Solving 18 + 5x2 = 20x Solving for variable 'x'. Reorder the terms: 18 + -20x + 5x2 = 20x + -20x Combine like terms: 20x + -20x = 0 18 + -20x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 3.6 + -4x + x2 = 0 Move the constant term to the right: Add '-3.6' to each side of the equation. 3.6 + -4x + -3.6 + x2 = 0 + -3.6 Reorder the terms: 3.6 + -3.6 + -4x + x2 = 0 + -3.6 Combine like terms: 3.6 + -3.6 = 0.0 0.0 + -4x + x2 = 0 + -3.6 -4x + x2 = 0 + -3.6 Combine like terms: 0 + -3.6 = -3.6 -4x + x2 = -3.6 The x term is -4x. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x + 4 + x2 = -3.6 + 4 Reorder the terms: 4 + -4x + x2 = -3.6 + 4 Combine like terms: -3.6 + 4 = 0.4 4 + -4x + x2 = 0.4 Factor a perfect square on the left side: (x + -2)(x + -2) = 0.4 Calculate the square root of the right side: 0.632455532 Break this problem into two subproblems by setting (x + -2) equal to 0.632455532 and -0.632455532.Subproblem 1
x + -2 = 0.632455532 Simplifying x + -2 = 0.632455532 Reorder the terms: -2 + x = 0.632455532 Solving -2 + x = 0.632455532 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = 0.632455532 + 2 Combine like terms: -2 + 2 = 0 0 + x = 0.632455532 + 2 x = 0.632455532 + 2 Combine like terms: 0.632455532 + 2 = 2.632455532 x = 2.632455532 Simplifying x = 2.632455532Subproblem 2
x + -2 = -0.632455532 Simplifying x + -2 = -0.632455532 Reorder the terms: -2 + x = -0.632455532 Solving -2 + x = -0.632455532 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x = -0.632455532 + 2 Combine like terms: -2 + 2 = 0 0 + x = -0.632455532 + 2 x = -0.632455532 + 2 Combine like terms: -0.632455532 + 2 = 1.367544468 x = 1.367544468 Simplifying x = 1.367544468Solution
