Simplifying 5x2 + 2x + -13 = 19 Reorder the terms: -13 + 2x + 5x2 = 19 Solving -13 + 2x + 5x2 = 19 Solving for variable 'x'. Reorder the terms: -13 + -19 + 2x + 5x2 = 19 + -19 Combine like terms: -13 + -19 = -32 -32 + 2x + 5x2 = 19 + -19 Combine like terms: 19 + -19 = 0 -32 + 2x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -6.4 + 0.4x + x2 = 0 Move the constant term to the right: Add '6.4' to each side of the equation. -6.4 + 0.4x + 6.4 + x2 = 0 + 6.4 Reorder the terms: -6.4 + 6.4 + 0.4x + x2 = 0 + 6.4 Combine like terms: -6.4 + 6.4 = 0.0 0.0 + 0.4x + x2 = 0 + 6.4 0.4x + x2 = 0 + 6.4 Combine like terms: 0 + 6.4 = 6.4 0.4x + x2 = 6.4 The x term is 0.4x. Take half its coefficient (0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. 0.4x + 0.04 + x2 = 6.4 + 0.04 Reorder the terms: 0.04 + 0.4x + x2 = 6.4 + 0.04 Combine like terms: 6.4 + 0.04 = 6.44 0.04 + 0.4x + x2 = 6.44 Factor a perfect square on the left side: (x + 0.2)(x + 0.2) = 6.44 Calculate the square root of the right side: 2.537715508 Break this problem into two subproblems by setting (x + 0.2) equal to 2.537715508 and -2.537715508.Subproblem 1
x + 0.2 = 2.537715508 Simplifying x + 0.2 = 2.537715508 Reorder the terms: 0.2 + x = 2.537715508 Solving 0.2 + x = 2.537715508 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + x = 2.537715508 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + x = 2.537715508 + -0.2 x = 2.537715508 + -0.2 Combine like terms: 2.537715508 + -0.2 = 2.337715508 x = 2.337715508 Simplifying x = 2.337715508Subproblem 2
x + 0.2 = -2.537715508 Simplifying x + 0.2 = -2.537715508 Reorder the terms: 0.2 + x = -2.537715508 Solving 0.2 + x = -2.537715508 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + x = -2.537715508 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + x = -2.537715508 + -0.2 x = -2.537715508 + -0.2 Combine like terms: -2.537715508 + -0.2 = -2.737715508 x = -2.737715508 Simplifying x = -2.737715508Solution
