Simplifying 5x2 + -2x = 470 Reorder the terms: -2x + 5x2 = 470 Solving -2x + 5x2 = 470 Solving for variable 'x'. Reorder the terms: -470 + -2x + 5x2 = 470 + -470 Combine like terms: 470 + -470 = 0 -470 + -2x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -94 + -0.4x + x2 = 0 Move the constant term to the right: Add '94' to each side of the equation. -94 + -0.4x + 94 + x2 = 0 + 94 Reorder the terms: -94 + 94 + -0.4x + x2 = 0 + 94 Combine like terms: -94 + 94 = 0 0 + -0.4x + x2 = 0 + 94 -0.4x + x2 = 0 + 94 Combine like terms: 0 + 94 = 94 -0.4x + x2 = 94 The x term is -0.4x. Take half its coefficient (-0.2). Square it (0.04) and add it to both sides. Add '0.04' to each side of the equation. -0.4x + 0.04 + x2 = 94 + 0.04 Reorder the terms: 0.04 + -0.4x + x2 = 94 + 0.04 Combine like terms: 94 + 0.04 = 94.04 0.04 + -0.4x + x2 = 94.04 Factor a perfect square on the left side: (x + -0.2)(x + -0.2) = 94.04 Calculate the square root of the right side: 9.697422338 Break this problem into two subproblems by setting (x + -0.2) equal to 9.697422338 and -9.697422338.Subproblem 1
x + -0.2 = 9.697422338 Simplifying x + -0.2 = 9.697422338 Reorder the terms: -0.2 + x = 9.697422338 Solving -0.2 + x = 9.697422338 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.2' to each side of the equation. -0.2 + 0.2 + x = 9.697422338 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + x = 9.697422338 + 0.2 x = 9.697422338 + 0.2 Combine like terms: 9.697422338 + 0.2 = 9.897422338 x = 9.897422338 Simplifying x = 9.897422338Subproblem 2
x + -0.2 = -9.697422338 Simplifying x + -0.2 = -9.697422338 Reorder the terms: -0.2 + x = -9.697422338 Solving -0.2 + x = -9.697422338 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.2' to each side of the equation. -0.2 + 0.2 + x = -9.697422338 + 0.2 Combine like terms: -0.2 + 0.2 = 0.0 0.0 + x = -9.697422338 + 0.2 x = -9.697422338 + 0.2 Combine like terms: -9.697422338 + 0.2 = -9.497422338 x = -9.497422338 Simplifying x = -9.497422338Solution
The solution to the problem is based on the solutions from the subproblems. x = {9.897422338, -9.497422338}
