Simplifying -16x2 + 16x + 25 = 0 Reorder the terms: 25 + 16x + -16x2 = 0 Solving 25 + 16x + -16x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -16 the coefficient of the squared term: Divide each side by '-16'. -1.5625 + -1x + x2 = 0 Move the constant term to the right: Add '1.5625' to each side of the equation. -1.5625 + -1x + 1.5625 + x2 = 0 + 1.5625 Reorder the terms: -1.5625 + 1.5625 + -1x + x2 = 0 + 1.5625 Combine like terms: -1.5625 + 1.5625 = 0.0000 0.0000 + -1x + x2 = 0 + 1.5625 -1x + x2 = 0 + 1.5625 Combine like terms: 0 + 1.5625 = 1.5625 -1x + x2 = 1.5625 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 = 1.5625 + 0.25 Reorder the terms: 0.25 + -1x + x2 = 1.5625 + 0.25 Combine like terms: 1.5625 + 0.25 = 1.8125 0.25 + -1x + x2 = 1.8125 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 1.8125 Calculate the square root of the right side: 1.346291202 Break this problem into two subproblems by setting (x + -0.5) equal to 1.346291202 and -1.346291202.Subproblem 1
x + -0.5 = 1.346291202 Simplifying x + -0.5 = 1.346291202 Reorder the terms: -0.5 + x = 1.346291202 Solving -0.5 + x = 1.346291202 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 = 1.346291202 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 1.346291202 + 0.5 x = 1.346291202 + 0.5 Combine like terms: 1.346291202 + 0.5 = 1.846291202 x = 1.846291202 Simplifying x = 1.846291202Subproblem 2
x + -0.5 = -1.346291202 Simplifying x + -0.5 = -1.346291202 Reorder the terms: -0.5 + x = -1.346291202 Solving -0.5 + x = -1.346291202 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 = -1.346291202 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -1.346291202 + 0.5 x = -1.346291202 + 0.5 Combine like terms: -1.346291202 + 0.5 = -0.846291202 x = -0.846291202 Simplifying x = -0.846291202Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.846291202, -0.846291202}
