Simplifying -0.2x2 + 12x + -20 = 7 Reorder the terms: -20 + 12x + -0.2x2 = 7 Solving -20 + 12x + -0.2x2 = 7 Solving for variable 'x'. Reorder the terms: -20 + -7 + 12x + -0.2x2 = 7 + -7 Combine like terms: -20 + -7 = -27 -27 + 12x + -0.2x2 = 7 + -7 Combine like terms: 7 + -7 = 0 -27 + 12x + -0.2x2 = 0 Begin completing the square. Divide all terms by -0.2 the coefficient of the squared term: Divide each side by '-0.2'. 135 + -60x + x2 = 0 Move the constant term to the right: Add '-135' to each side of the equation. 135 + -60x + -135 + x2 = 0 + -135 Reorder the terms: 135 + -135 + -60x + x2 = 0 + -135 Combine like terms: 135 + -135 = 0 0 + -60x + x2 = 0 + -135 -60x + x2 = 0 + -135 Combine like terms: 0 + -135 = -135 -60x + x2 = -135 The x term is -60x. Take half its coefficient (-30). Square it (900) and add it to both sides. Add '900' to each side of the equation. -60x + 900 + x2 = -135 + 900 Reorder the terms: 900 + -60x + x2 = -135 + 900 Combine like terms: -135 + 900 = 765 900 + -60x + x2 = 765 Factor a perfect square on the left side: (x + -30)(x + -30) = 765 Calculate the square root of the right side: 27.658633372 Break this problem into two subproblems by setting (x + -30) equal to 27.658633372 and -27.658633372.Subproblem 1
x + -30 = 27.658633372 Simplifying x + -30 = 27.658633372 Reorder the terms: -30 + x = 27.658633372 Solving -30 + x = 27.658633372 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '30' to each side of the equation. -30 + 30 + x = 27.658633372 + 30 Combine like terms: -30 + 30 = 0 0 + x = 27.658633372 + 30 x = 27.658633372 + 30 Combine like terms: 27.658633372 + 30 = 57.658633372 x = 57.658633372 Simplifying x = 57.658633372Subproblem 2
x + -30 = -27.658633372 Simplifying x + -30 = -27.658633372 Reorder the terms: -30 + x = -27.658633372 Solving -30 + x = -27.658633372 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '30' to each side of the equation. -30 + 30 + x = -27.658633372 + 30 Combine like terms: -30 + 30 = 0 0 + x = -27.658633372 + 30 x = -27.658633372 + 30 Combine like terms: -27.658633372 + 30 = 2.341366628 x = 2.341366628 Simplifying x = 2.341366628Solution
