Simplifying 10x(x + -4) = 9x + -2 Reorder the terms: 10x(-4 + x) = 9x + -2 (-4 * 10x + x * 10x) = 9x + -2 (-40x + 10x2) = 9x + -2 Reorder the terms: -40x + 10x2 = -2 + 9x Solving -40x + 10x2 = -2 + 9x Solving for variable 'x'. Reorder the terms: 2 + -40x + -9x + 10x2 = -2 + 9x + 2 + -9x Combine like terms: -40x + -9x = -49x 2 + -49x + 10x2 = -2 + 9x + 2 + -9x Reorder the terms: 2 + -49x + 10x2 = -2 + 2 + 9x + -9x Combine like terms: -2 + 2 = 0 2 + -49x + 10x2 = 0 + 9x + -9x 2 + -49x + 10x2 = 9x + -9x Combine like terms: 9x + -9x = 0 2 + -49x + 10x2 = 0 Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. 0.2 + -4.9x + x2 = 0 Move the constant term to the right: Add '-0.2' to each side of the equation. 0.2 + -4.9x + -0.2 + x2 = 0 + -0.2 Reorder the terms: 0.2 + -0.2 + -4.9x + x2 = 0 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + -4.9x + x2 = 0 + -0.2 -4.9x + x2 = 0 + -0.2 Combine like terms: 0 + -0.2 = -0.2 -4.9x + x2 = -0.2 The x term is -4.9x. Take half its coefficient (-2.45). Square it (6.0025) and add it to both sides. Add '6.0025' to each side of the equation. -4.9x + 6.0025 + x2 = -0.2 + 6.0025 Reorder the terms: 6.0025 + -4.9x + x2 = -0.2 + 6.0025 Combine like terms: -0.2 + 6.0025 = 5.8025 6.0025 + -4.9x + x2 = 5.8025 Factor a perfect square on the left side: (x + -2.45)(x + -2.45) = 5.8025 Calculate the square root of the right side: 2.408837894 Break this problem into two subproblems by setting (x + -2.45) equal to 2.408837894 and -2.408837894.Subproblem 1
x + -2.45 = 2.408837894 Simplifying x + -2.45 = 2.408837894 Reorder the terms: -2.45 + x = 2.408837894 Solving -2.45 + x = 2.408837894 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.45' to each side of the equation. -2.45 + 2.45 + x = 2.408837894 + 2.45 Combine like terms: -2.45 + 2.45 = 0.00 0.00 + x = 2.408837894 + 2.45 x = 2.408837894 + 2.45 Combine like terms: 2.408837894 + 2.45 = 4.858837894 x = 4.858837894 Simplifying x = 4.858837894Subproblem 2
x + -2.45 = -2.408837894 Simplifying x + -2.45 = -2.408837894 Reorder the terms: -2.45 + x = -2.408837894 Solving -2.45 + x = -2.408837894 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.45' to each side of the equation. -2.45 + 2.45 + x = -2.408837894 + 2.45 Combine like terms: -2.45 + 2.45 = 0.00 0.00 + x = -2.408837894 + 2.45 x = -2.408837894 + 2.45 Combine like terms: -2.408837894 + 2.45 = 0.041162106 x = 0.041162106 Simplifying x = 0.041162106Solution
