Simplifying x2 + 9x + 15 + x = 11 Reorder the terms: 15 + 9x + x + x2 = 11 Combine like terms: 9x + x = 10x 15 + 10x + x2 = 11 Solving 15 + 10x + x2 = 11 Solving for variable 'x'. Reorder the terms: 15 + -11 + 10x + x2 = 11 + -11 Combine like terms: 15 + -11 = 4 4 + 10x + x2 = 11 + -11 Combine like terms: 11 + -11 = 0 4 + 10x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-4' to each side of the equation. 4 + 10x + -4 + x2 = 0 + -4 Reorder the terms: 4 + -4 + 10x + x2 = 0 + -4 Combine like terms: 4 + -4 = 0 0 + 10x + x2 = 0 + -4 10x + x2 = 0 + -4 Combine like terms: 0 + -4 = -4 10x + x2 = -4 The x term is 10x. Take half its coefficient (5). Square it (25) and add it to both sides. Add '25' to each side of the equation. 10x + 25 + x2 = -4 + 25 Reorder the terms: 25 + 10x + x2 = -4 + 25 Combine like terms: -4 + 25 = 21 25 + 10x + x2 = 21 Factor a perfect square on the left side: (x + 5)(x + 5) = 21 Calculate the square root of the right side: 4.582575695 Break this problem into two subproblems by setting (x + 5) equal to 4.582575695 and -4.582575695.Subproblem 1
x + 5 = 4.582575695 Simplifying x + 5 = 4.582575695 Reorder the terms: 5 + x = 4.582575695 Solving 5 + x = 4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = 4.582575695 + -5 Combine like terms: 5 + -5 = 0 0 + x = 4.582575695 + -5 x = 4.582575695 + -5 Combine like terms: 4.582575695 + -5 = -0.417424305 x = -0.417424305 Simplifying x = -0.417424305Subproblem 2
x + 5 = -4.582575695 Simplifying x + 5 = -4.582575695 Reorder the terms: 5 + x = -4.582575695 Solving 5 + x = -4.582575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x = -4.582575695 + -5 Combine like terms: 5 + -5 = 0 0 + x = -4.582575695 + -5 x = -4.582575695 + -5 Combine like terms: -4.582575695 + -5 = -9.582575695 x = -9.582575695 Simplifying x = -9.582575695Solution
