Simplifying 16x2 + 6x = 13 Reorder the terms: 6x + 16x2 = 13 Solving 6x + 16x2 = 13 Solving for variable 'x'. Reorder the terms: -13 + 6x + 16x2 = 13 + -13 Combine like terms: 13 + -13 = 0 -13 + 6x + 16x2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -0.8125 + 0.375x + x2 = 0 Move the constant term to the right: Add '0.8125' to each side of the equation. -0.8125 + 0.375x + 0.8125 + x2 = 0 + 0.8125 Reorder the terms: -0.8125 + 0.8125 + 0.375x + x2 = 0 + 0.8125 Combine like terms: -0.8125 + 0.8125 = 0.0000 0.0000 + 0.375x + x2 = 0 + 0.8125 0.375x + x2 = 0 + 0.8125 Combine like terms: 0 + 0.8125 = 0.8125 0.375x + x2 = 0.8125 The x term is 0.375x. Take half its coefficient (0.1875). Square it (0.03515625) and add it to both sides. Add '0.03515625' to each side of the equation. 0.375x + 0.03515625 + x2 = 0.8125 + 0.03515625 Reorder the terms: 0.03515625 + 0.375x + x2 = 0.8125 + 0.03515625 Combine like terms: 0.8125 + 0.03515625 = 0.84765625 0.03515625 + 0.375x + x2 = 0.84765625 Factor a perfect square on the left side: (x + 0.1875)(x + 0.1875) = 0.84765625 Calculate the square root of the right side: 0.920682491 Break this problem into two subproblems by setting (x + 0.1875) equal to 0.920682491 and -0.920682491.Subproblem 1
x + 0.1875 = 0.920682491 Simplifying x + 0.1875 = 0.920682491 Reorder the terms: 0.1875 + x = 0.920682491 Solving 0.1875 + x = 0.920682491 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.1875' to each side of the equation. 0.1875 + -0.1875 + x = 0.920682491 + -0.1875 Combine like terms: 0.1875 + -0.1875 = 0.0000 0.0000 + x = 0.920682491 + -0.1875 x = 0.920682491 + -0.1875 Combine like terms: 0.920682491 + -0.1875 = 0.733182491 x = 0.733182491 Simplifying x = 0.733182491Subproblem 2
x + 0.1875 = -0.920682491 Simplifying x + 0.1875 = -0.920682491 Reorder the terms: 0.1875 + x = -0.920682491 Solving 0.1875 + x = -0.920682491 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.1875' to each side of the equation. 0.1875 + -0.1875 + x = -0.920682491 + -0.1875 Combine like terms: 0.1875 + -0.1875 = 0.0000 0.0000 + x = -0.920682491 + -0.1875 x = -0.920682491 + -0.1875 Combine like terms: -0.920682491 + -0.1875 = -1.108182491 x = -1.108182491 Simplifying x = -1.108182491Solution
