Simplifying 5x2 + -15x + -45 = 0 Reorder the terms: -45 + -15x + 5x2 = 0 Solving -45 + -15x + 5x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '5'. 5(-9 + -3x + x2) = 0 Ignore the factor 5.Subproblem 1
Set the factor '(-9 + -3x + x2)' equal to zero and attempt to solve: Simplifying -9 + -3x + x2 = 0 Solving -9 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '9' to each side of the equation. -9 + -3x + 9 + x2 = 0 + 9 Reorder the terms: -9 + 9 + -3x + x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -3x + x2 = 0 + 9 -3x + x2 = 0 + 9 Combine like terms: 0 + 9 = 9 -3x + x2 = 9 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = 9 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 9 + 2.25 Combine like terms: 9 + 2.25 = 11.25 2.25 + -3x + x2 = 11.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 11.25 Calculate the square root of the right side: 3.354101966 Break this problem into two subproblems by setting (x + -1.5) equal to 3.354101966 and -3.354101966.Subproblem 1
x + -1.5 = 3.354101966 Simplifying x + -1.5 = 3.354101966 Reorder the terms: -1.5 + x = 3.354101966 Solving -1.5 + x = 3.354101966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 3.354101966 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 3.354101966 + 1.5 x = 3.354101966 + 1.5 Combine like terms: 3.354101966 + 1.5 = 4.854101966 x = 4.854101966 Simplifying x = 4.854101966Subproblem 2
x + -1.5 = -3.354101966 Simplifying x + -1.5 = -3.354101966 Reorder the terms: -1.5 + x = -3.354101966 Solving -1.5 + x = -3.354101966 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -3.354101966 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -3.354101966 + 1.5 x = -3.354101966 + 1.5 Combine like terms: -3.354101966 + 1.5 = -1.854101966 x = -1.854101966 Simplifying x = -1.854101966Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.854101966, -1.854101966}Solution
x = {4.854101966, -1.854101966}
