Simplifying -5x2 + 6x + 5 = 0 Reorder the terms: 5 + 6x + -5x2 = 0 Solving 5 + 6x + -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'. -1 + -1.2x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + -1.2x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -1.2x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1.2x + x2 = 0 + 1 -1.2x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -1.2x + x2 = 1 The x term is -1.2x. Take half its coefficient (-0.6). Square it (0.36) and add it to both sides. Add '0.36' to each side of the equation. -1.2x + 0.36 + x2 = 1 + 0.36 Reorder the terms: 0.36 + -1.2x + x2 = 1 + 0.36 Combine like terms: 1 + 0.36 = 1.36 0.36 + -1.2x + x2 = 1.36 Factor a perfect square on the left side: (x + -0.6)(x + -0.6) = 1.36 Calculate the square root of the right side: 1.166190379 Break this problem into two subproblems by setting (x + -0.6) equal to 1.166190379 and -1.166190379.Subproblem 1
x + -0.6 = 1.166190379 Simplifying x + -0.6 = 1.166190379 Reorder the terms: -0.6 + x = 1.166190379 Solving -0.6 + x = 1.166190379 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.6' to each side of the equation. -0.6 + 0.6 + x = 1.166190379 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + x = 1.166190379 + 0.6 x = 1.166190379 + 0.6 Combine like terms: 1.166190379 + 0.6 = 1.766190379 x = 1.766190379 Simplifying x = 1.766190379Subproblem 2
x + -0.6 = -1.166190379 Simplifying x + -0.6 = -1.166190379 Reorder the terms: -0.6 + x = -1.166190379 Solving -0.6 + x = -1.166190379 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.6' to each side of the equation. -0.6 + 0.6 + x = -1.166190379 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + x = -1.166190379 + 0.6 x = -1.166190379 + 0.6 Combine like terms: -1.166190379 + 0.6 = -0.566190379 x = -0.566190379 Simplifying x = -0.566190379Solution
The solution to the problem is based on the solutions from the subproblems. x = {1.766190379, -0.566190379}
