Simplifying (5x2 + 8x + -64) = 0 Reorder the terms: (-64 + 8x + 5x2) = 0 Remove parenthesis around (-64 + 8x + 5x2) -64 + 8x + 5x2 = 0 Solving -64 + 8x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -12.8 + 1.6x + x2 = 0 Move the constant term to the right: Add '12.8' to each side of the equation. -12.8 + 1.6x + 12.8 + x2 = 0 + 12.8 Reorder the terms: -12.8 + 12.8 + 1.6x + x2 = 0 + 12.8 Combine like terms: -12.8 + 12.8 = 0.0 0.0 + 1.6x + x2 = 0 + 12.8 1.6x + x2 = 0 + 12.8 Combine like terms: 0 + 12.8 = 12.8 1.6x + x2 = 12.8 The x term is 1.6x. Take half its coefficient (0.8). Square it (0.64) and add it to both sides. Add '0.64' to each side of the equation. 1.6x + 0.64 + x2 = 12.8 + 0.64 Reorder the terms: 0.64 + 1.6x + x2 = 12.8 + 0.64 Combine like terms: 12.8 + 0.64 = 13.44 0.64 + 1.6x + x2 = 13.44 Factor a perfect square on the left side: (x + 0.8)(x + 0.8) = 13.44 Calculate the square root of the right side: 3.666060556 Break this problem into two subproblems by setting (x + 0.8) equal to 3.666060556 and -3.666060556.Subproblem 1
x + 0.8 = 3.666060556 Simplifying x + 0.8 = 3.666060556 Reorder the terms: 0.8 + x = 3.666060556 Solving 0.8 + x = 3.666060556 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.8' to each side of the equation. 0.8 + -0.8 + x = 3.666060556 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + x = 3.666060556 + -0.8 x = 3.666060556 + -0.8 Combine like terms: 3.666060556 + -0.8 = 2.866060556 x = 2.866060556 Simplifying x = 2.866060556Subproblem 2
x + 0.8 = -3.666060556 Simplifying x + 0.8 = -3.666060556 Reorder the terms: 0.8 + x = -3.666060556 Solving 0.8 + x = -3.666060556 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.8' to each side of the equation. 0.8 + -0.8 + x = -3.666060556 + -0.8 Combine like terms: 0.8 + -0.8 = 0.0 0.0 + x = -3.666060556 + -0.8 x = -3.666060556 + -0.8 Combine like terms: -3.666060556 + -0.8 = -4.466060556 x = -4.466060556 Simplifying x = -4.466060556Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.866060556, -4.466060556}
