Simplifying x2 + 5x + -915 = 0 Reorder the terms: -915 + 5x + x2 = 0 Solving -915 + 5x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '915' to each side of the equation. -915 + 5x + 915 + x2 = 0 + 915 Reorder the terms: -915 + 915 + 5x + x2 = 0 + 915 Combine like terms: -915 + 915 = 0 0 + 5x + x2 = 0 + 915 5x + x2 = 0 + 915 Combine like terms: 0 + 915 = 915 5x + x2 = 915 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 = 915 + 6.25 Reorder the terms: 6.25 + 5x + x2 = 915 + 6.25 Combine like terms: 915 + 6.25 = 921.25 6.25 + 5x + x2 = 921.25 Factor a perfect square on the left side: (x + 2.5)(x + 2.5) = 921.25 Calculate the square root of the right side: 30.352100422 Break this problem into two subproblems by setting (x + 2.5) equal to 30.352100422 and -30.352100422.Subproblem 1
x + 2.5 = 30.352100422 Simplifying x + 2.5 = 30.352100422 Reorder the terms: 2.5 + x = 30.352100422 Solving 2.5 + x = 30.352100422 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 = 30.352100422 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = 30.352100422 + -2.5 x = 30.352100422 + -2.5 Combine like terms: 30.352100422 + -2.5 = 27.852100422 x = 27.852100422 Simplifying x = 27.852100422Subproblem 2
x + 2.5 = -30.352100422 Simplifying x + 2.5 = -30.352100422 Reorder the terms: 2.5 + x = -30.352100422 Solving 2.5 + x = -30.352100422 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 = -30.352100422 + -2.5 Combine like terms: 2.5 + -2.5 = 0.0 0.0 + x = -30.352100422 + -2.5 x = -30.352100422 + -2.5 Combine like terms: -30.352100422 + -2.5 = -32.852100422 x = -32.852100422 Simplifying x = -32.852100422Solution
