Simplifying 2x2 + -20x + -3 = 0 Reorder the terms: -3 + -20x + 2x2 = 0 Solving -3 + -20x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -1.5 + -10x + x2 = 0 Move the constant term to the right: Add '1.5' to each side of the equation. -1.5 + -10x + 1.5 + x2 = 0 + 1.5 Reorder the terms: -1.5 + 1.5 + -10x + x2 = 0 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + -10x + x2 = 0 + 1.5 -10x + x2 = 0 + 1.5 Combine like terms: 0 + 1.5 = 1.5 -10x + x2 = 1.5 The x term is -10x. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10x + 25 + x2 = 1.5 + 25 Reorder the terms: 25 + -10x + x2 = 1.5 + 25 Combine like terms: 1.5 + 25 = 26.5 25 + -10x + x2 = 26.5 Factor a perfect square on the left side: (x + -5)(x + -5) = 26.5 Calculate the square root of the right side: 5.14781507 Break this problem into two subproblems by setting (x + -5) equal to 5.14781507 and -5.14781507.Subproblem 1
x + -5 = 5.14781507 Simplifying x + -5 = 5.14781507 Reorder the terms: -5 + x = 5.14781507 Solving -5 + x = 5.14781507 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = 5.14781507 + 5 Combine like terms: -5 + 5 = 0 0 + x = 5.14781507 + 5 x = 5.14781507 + 5 Combine like terms: 5.14781507 + 5 = 10.14781507 x = 10.14781507 Simplifying x = 10.14781507Subproblem 2
x + -5 = -5.14781507 Simplifying x + -5 = -5.14781507 Reorder the terms: -5 + x = -5.14781507 Solving -5 + x = -5.14781507 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = -5.14781507 + 5 Combine like terms: -5 + 5 = 0 0 + x = -5.14781507 + 5 x = -5.14781507 + 5 Combine like terms: -5.14781507 + 5 = -0.14781507 x = -0.14781507 Simplifying x = -0.14781507Solution
