Simplifying 8x2 = x + 5 Reorder the terms: 8x2 = 5 + x Solving 8x2 = 5 + x Solving for variable 'x'. Reorder the terms: -5 + -1x + 8x2 = 5 + x + -5 + -1x Reorder the terms: -5 + -1x + 8x2 = 5 + -5 + x + -1x Combine like terms: 5 + -5 = 0 -5 + -1x + 8x2 = 0 + x + -1x -5 + -1x + 8x2 = x + -1x Combine like terms: x + -1x = 0 -5 + -1x + 8x2 = 0 Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -0.625 + -0.125x + x2 = 0 Move the constant term to the right: Add '0.625' to each side of the equation. -0.625 + -0.125x + 0.625 + x2 = 0 + 0.625 Reorder the terms: -0.625 + 0.625 + -0.125x + x2 = 0 + 0.625 Combine like terms: -0.625 + 0.625 = 0.000 0.000 + -0.125x + x2 = 0 + 0.625 -0.125x + x2 = 0 + 0.625 Combine like terms: 0 + 0.625 = 0.625 -0.125x + x2 = 0.625 The x term is -0.125x. Take half its coefficient (-0.0625). Square it (0.00390625) and add it to both sides. Add '0.00390625' to each side of the equation. -0.125x + 0.00390625 + x2 = 0.625 + 0.00390625 Reorder the terms: 0.00390625 + -0.125x + x2 = 0.625 + 0.00390625 Combine like terms: 0.625 + 0.00390625 = 0.62890625 0.00390625 + -0.125x + x2 = 0.62890625 Factor a perfect square on the left side: (x + -0.0625)(x + -0.0625) = 0.62890625 Calculate the square root of the right side: 0.793036096 Break this problem into two subproblems by setting (x + -0.0625) equal to 0.793036096 and -0.793036096.Subproblem 1
x + -0.0625 = 0.793036096 Simplifying x + -0.0625 = 0.793036096 Reorder the terms: -0.0625 + x = 0.793036096 Solving -0.0625 + x = 0.793036096 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.0625' to each side of the equation. -0.0625 + 0.0625 + x = 0.793036096 + 0.0625 Combine like terms: -0.0625 + 0.0625 = 0.0000 0.0000 + x = 0.793036096 + 0.0625 x = 0.793036096 + 0.0625 Combine like terms: 0.793036096 + 0.0625 = 0.855536096 x = 0.855536096 Simplifying x = 0.855536096Subproblem 2
x + -0.0625 = -0.793036096 Simplifying x + -0.0625 = -0.793036096 Reorder the terms: -0.0625 + x = -0.793036096 Solving -0.0625 + x = -0.793036096 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.0625' to each side of the equation. -0.0625 + 0.0625 + x = -0.793036096 + 0.0625 Combine like terms: -0.0625 + 0.0625 = 0.0000 0.0000 + x = -0.793036096 + 0.0625 x = -0.793036096 + 0.0625 Combine like terms: -0.793036096 + 0.0625 = -0.730536096 x = -0.730536096 Simplifying x = -0.730536096Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.855536096, -0.730536096}
