Simplifying 5x(2x + -9) = x2 + -5 Reorder the terms: 5x(-9 + 2x) = x2 + -5 (-9 * 5x + 2x * 5x) = x2 + -5 (-45x + 10x2) = x2 + -5 Reorder the terms: -45x + 10x2 = -5 + x2 Solving -45x + 10x2 = -5 + x2 Solving for variable 'x'. Reorder the terms: 5 + -45x + 10x2 + -1x2 = -5 + x2 + 5 + -1x2 Combine like terms: 10x2 + -1x2 = 9x2 5 + -45x + 9x2 = -5 + x2 + 5 + -1x2 Reorder the terms: 5 + -45x + 9x2 = -5 + 5 + x2 + -1x2 Combine like terms: -5 + 5 = 0 5 + -45x + 9x2 = 0 + x2 + -1x2 5 + -45x + 9x2 = x2 + -1x2 Combine like terms: x2 + -1x2 = 0 5 + -45x + 9x2 = 0 Begin completing the square. Divide all terms by 9 the coefficient of the squared term: Divide each side by '9'. 0.5555555556 + -5x + x2 = 0 Move the constant term to the right: Add '-0.5555555556' to each side of the equation. 0.5555555556 + -5x + -0.5555555556 + x2 = 0 + -0.5555555556 Reorder the terms: 0.5555555556 + -0.5555555556 + -5x + x2 = 0 + -0.5555555556 Combine like terms: 0.5555555556 + -0.5555555556 = 0.0000000000 0.0000000000 + -5x + x2 = 0 + -0.5555555556 -5x + x2 = 0 + -0.5555555556 Combine like terms: 0 + -0.5555555556 = -0.5555555556 -5x + x2 = -0.5555555556 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = -0.5555555556 + 6.25 Reorder the terms: 6.25 + -5x + x2 = -0.5555555556 + 6.25 Combine like terms: -0.5555555556 + 6.25 = 5.6944444444 6.25 + -5x + x2 = 5.6944444444 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 5.6944444444 Calculate the square root of the right side: 2.386303511 Break this problem into two subproblems by setting (x + -2.5) equal to 2.386303511 and -2.386303511.Subproblem 1
x + -2.5 = 2.386303511 Simplifying x + -2.5 = 2.386303511 Reorder the terms: -2.5 + x = 2.386303511 Solving -2.5 + x = 2.386303511 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 2.386303511 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 2.386303511 + 2.5 x = 2.386303511 + 2.5 Combine like terms: 2.386303511 + 2.5 = 4.886303511 x = 4.886303511 Simplifying x = 4.886303511Subproblem 2
x + -2.5 = -2.386303511 Simplifying x + -2.5 = -2.386303511 Reorder the terms: -2.5 + x = -2.386303511 Solving -2.5 + x = -2.386303511 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -2.386303511 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -2.386303511 + 2.5 x = -2.386303511 + 2.5 Combine like terms: -2.386303511 + 2.5 = 0.113696489 x = 0.113696489 Simplifying x = 0.113696489Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.886303511, 0.113696489}
