Simplifying 40x2 + -49x + -40 = 0 Reorder the terms: -40 + -49x + 40x2 = 0 Solving -40 + -49x + 40x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 40 the coefficient of the squared term: Divide each side by '40'. -1 + -1.225x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + -1.225x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -1.225x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1.225x + x2 = 0 + 1 -1.225x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -1.225x + x2 = 1 The x term is -1.225x. Take half its coefficient (-0.6125). Square it (0.37515625) and add it to both sides. Add '0.37515625' to each side of the equation. -1.225x + 0.37515625 + x2 = 1 + 0.37515625 Reorder the terms: 0.37515625 + -1.225x + x2 = 1 + 0.37515625 Combine like terms: 1 + 0.37515625 = 1.37515625 0.37515625 + -1.225x + x2 = 1.37515625 Factor a perfect square on the left side: (x + -0.6125)(x + -0.6125) = 1.37515625 Calculate the square root of the right side: 1.172670563 Break this problem into two subproblems by setting (x + -0.6125) equal to 1.172670563 and -1.172670563.Subproblem 1
x + -0.6125 = 1.172670563 Simplifying x + -0.6125 = 1.172670563 Reorder the terms: -0.6125 + x = 1.172670563 Solving -0.6125 + x = 1.172670563 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.6125' to each side of the equation. -0.6125 + 0.6125 + x = 1.172670563 + 0.6125 Combine like terms: -0.6125 + 0.6125 = 0.0000 0.0000 + x = 1.172670563 + 0.6125 x = 1.172670563 + 0.6125 Combine like terms: 1.172670563 + 0.6125 = 1.785170563 x = 1.785170563 Simplifying x = 1.785170563Subproblem 2
x + -0.6125 = -1.172670563 Simplifying x + -0.6125 = -1.172670563 Reorder the terms: -0.6125 + x = -1.172670563 Solving -0.6125 + x = -1.172670563 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.6125' to each side of the equation. -0.6125 + 0.6125 + x = -1.172670563 + 0.6125 Combine like terms: -0.6125 + 0.6125 = 0.0000 0.0000 + x = -1.172670563 + 0.6125 x = -1.172670563 + 0.6125 Combine like terms: -1.172670563 + 0.6125 = -0.560170563 x = -0.560170563 Simplifying x = -0.560170563Solution
