Simplifying 16x2 + -8x + -8x + 4 = 39 Reorder the terms: 4 + -8x + -8x + 16x2 = 39 Combine like terms: -8x + -8x = -16x 4 + -16x + 16x2 = 39 Solving 4 + -16x + 16x2 = 39 Solving for variable 'x'. Reorder the terms: 4 + -39 + -16x + 16x2 = 39 + -39 Combine like terms: 4 + -39 = -35 -35 + -16x + 16x2 = 39 + -39 Combine like terms: 39 + -39 = 0 -35 + -16x + 16x2 = 0 Begin completing the square. Divide all terms by 16 the coefficient of the squared term: Divide each side by '16'. -2.1875 + -1x + x2 = 0 Move the constant term to the right: Add '2.1875' to each side of the equation. -2.1875 + -1x + 2.1875 + x2 = 0 + 2.1875 Reorder the terms: -2.1875 + 2.1875 + -1x + x2 = 0 + 2.1875 Combine like terms: -2.1875 + 2.1875 = 0.0000 0.0000 + -1x + x2 = 0 + 2.1875 -1x + x2 = 0 + 2.1875 Combine like terms: 0 + 2.1875 = 2.1875 -1x + x2 = 2.1875 The x term is -1x. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x + 0.25 + x2 = 2.1875 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 2.1875 + 0.25 Combine like terms: 2.1875 + 0.25 = 2.4375 0.25 + -1x + x2 = 2.4375 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 2.4375 Calculate the square root of the right side: 1.5612495 Break this problem into two subproblems by setting (x + -0.5) equal to 1.5612495 and -1.5612495.Subproblem 1
x + -0.5 = 1.5612495 Simplifying x + -0.5 = 1.5612495 Reorder the terms: -0.5 + x = 1.5612495 Solving -0.5 + x = 1.5612495 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = 1.5612495 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 1.5612495 + 0.5 x = 1.5612495 + 0.5 Combine like terms: 1.5612495 + 0.5 = 2.0612495 x = 2.0612495 Simplifying x = 2.0612495Subproblem 2
x + -0.5 = -1.5612495 Simplifying x + -0.5 = -1.5612495 Reorder the terms: -0.5 + x = -1.5612495 Solving -0.5 + x = -1.5612495 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + x = -1.5612495 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -1.5612495 + 0.5 x = -1.5612495 + 0.5 Combine like terms: -1.5612495 + 0.5 = -1.0612495 x = -1.0612495 Simplifying x = -1.0612495Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.0612495, -1.0612495}
