Simplifying 20x2 + -19x + -3 = 0 Reorder the terms: -3 + -19x + 20x2 = 0 Solving -3 + -19x + 20x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -0.15 + -0.95x + x2 = 0 Move the constant term to the right: Add '0.15' to each side of the equation. -0.15 + -0.95x + 0.15 + x2 = 0 + 0.15 Reorder the terms: -0.15 + 0.15 + -0.95x + x2 = 0 + 0.15 Combine like terms: -0.15 + 0.15 = 0.00 0.00 + -0.95x + x2 = 0 + 0.15 -0.95x + x2 = 0 + 0.15 Combine like terms: 0 + 0.15 = 0.15 -0.95x + x2 = 0.15 The x term is -0.95x. Take half its coefficient (-0.475). Square it (0.225625) and add it to both sides. Add '0.225625' to each side of the equation. -0.95x + 0.225625 + x2 = 0.15 + 0.225625 Reorder the terms: 0.225625 + -0.95x + x2 = 0.15 + 0.225625 Combine like terms: 0.15 + 0.225625 = 0.375625 0.225625 + -0.95x + x2 = 0.375625 Factor a perfect square on the left side: (x + -0.475)(x + -0.475) = 0.375625 Calculate the square root of the right side: 0.612882534 Break this problem into two subproblems by setting (x + -0.475) equal to 0.612882534 and -0.612882534.Subproblem 1
x + -0.475 = 0.612882534 Simplifying x + -0.475 = 0.612882534 Reorder the terms: -0.475 + x = 0.612882534 Solving -0.475 + x = 0.612882534 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.475' to each side of the equation. -0.475 + 0.475 + x = 0.612882534 + 0.475 Combine like terms: -0.475 + 0.475 = 0.000 0.000 + x = 0.612882534 + 0.475 x = 0.612882534 + 0.475 Combine like terms: 0.612882534 + 0.475 = 1.087882534 x = 1.087882534 Simplifying x = 1.087882534Subproblem 2
x + -0.475 = -0.612882534 Simplifying x + -0.475 = -0.612882534 Reorder the terms: -0.475 + x = -0.612882534 Solving -0.475 + x = -0.612882534 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.475' to each side of the equation. -0.475 + 0.475 + x = -0.612882534 + 0.475 Combine like terms: -0.475 + 0.475 = 0.000 0.000 + x = -0.612882534 + 0.475 x = -0.612882534 + 0.475 Combine like terms: -0.612882534 + 0.475 = -0.137882534 x = -0.137882534 Simplifying x = -0.137882534Solution
