Simplifying 4x2 + -8x + -13 = 0 Reorder the terms: -13 + -8x + 4x2 = 0 Solving -13 + -8x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -3.25 + -2x + x2 = 0 Move the constant term to the right: Add '3.25' to each side of the equation. -3.25 + -2x + 3.25 + x2 = 0 + 3.25 Reorder the terms: -3.25 + 3.25 + -2x + x2 = 0 + 3.25 Combine like terms: -3.25 + 3.25 = 0.00 0.00 + -2x + x2 = 0 + 3.25 -2x + x2 = 0 + 3.25 Combine like terms: 0 + 3.25 = 3.25 -2x + x2 = 3.25 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 3.25 + 1 Reorder the terms: 1 + -2x + x2 = 3.25 + 1 Combine like terms: 3.25 + 1 = 4.25 1 + -2x + x2 = 4.25 Factor a perfect square on the left side: (x + -1)(x + -1) = 4.25 Calculate the square root of the right side: 2.061552813 Break this problem into two subproblems by setting (x + -1) equal to 2.061552813 and -2.061552813.Subproblem 1
x + -1 = 2.061552813 Simplifying x + -1 = 2.061552813 Reorder the terms: -1 + x = 2.061552813 Solving -1 + x = 2.061552813 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 2.061552813 + 1 Combine like terms: -1 + 1 = 0 0 + x = 2.061552813 + 1 x = 2.061552813 + 1 Combine like terms: 2.061552813 + 1 = 3.061552813 x = 3.061552813 Simplifying x = 3.061552813Subproblem 2
x + -1 = -2.061552813 Simplifying x + -1 = -2.061552813 Reorder the terms: -1 + x = -2.061552813 Solving -1 + x = -2.061552813 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -2.061552813 + 1 Combine like terms: -1 + 1 = 0 0 + x = -2.061552813 + 1 x = -2.061552813 + 1 Combine like terms: -2.061552813 + 1 = -1.061552813 x = -1.061552813 Simplifying x = -1.061552813Solution
