Simplifying x2 + 9x = 336 Reorder the terms: 9x + x2 = 336 Solving 9x + x2 = 336 Solving for variable 'x'. Reorder the terms: -336 + 9x + x2 = 336 + -336 Combine like terms: 336 + -336 = 0 -336 + 9x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '336' to each side of the equation. -336 + 9x + 336 + x2 = 0 + 336 Reorder the terms: -336 + 336 + 9x + x2 = 0 + 336 Combine like terms: -336 + 336 = 0 0 + 9x + x2 = 0 + 336 9x + x2 = 0 + 336 Combine like terms: 0 + 336 = 336 9x + x2 = 336 The x term is 9x. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9x + 20.25 + x2 = 336 + 20.25 Reorder the terms: 20.25 + 9x + x2 = 336 + 20.25 Combine like terms: 336 + 20.25 = 356.25 20.25 + 9x + x2 = 356.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 356.25 Calculate the square root of the right side: 18.874586088 Break this problem into two subproblems by setting (x + 4.5) equal to 18.874586088 and -18.874586088.Subproblem 1
x + 4.5 = 18.874586088 Simplifying x + 4.5 = 18.874586088 Reorder the terms: 4.5 + x = 18.874586088 Solving 4.5 + x = 18.874586088 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = 18.874586088 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 18.874586088 + -4.5 x = 18.874586088 + -4.5 Combine like terms: 18.874586088 + -4.5 = 14.374586088 x = 14.374586088 Simplifying x = 14.374586088Subproblem 2
x + 4.5 = -18.874586088 Simplifying x + 4.5 = -18.874586088 Reorder the terms: 4.5 + x = -18.874586088 Solving 4.5 + x = -18.874586088 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = -18.874586088 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -18.874586088 + -4.5 x = -18.874586088 + -4.5 Combine like terms: -18.874586088 + -4.5 = -23.374586088 x = -23.374586088 Simplifying x = -23.374586088Solution
