Simplifying 18 = x4 + 9x2 Reorder the terms: 18 = 9x2 + x4 Solving 18 = 9x2 + x4 Solving for variable 'x'. Reorder the terms: 18 + -9x2 + -1x4 = 9x2 + -9x2 + x4 + -1x4 Combine like terms: 9x2 + -9x2 = 0 18 + -9x2 + -1x4 = 0 + x4 + -1x4 18 + -9x2 + -1x4 = x4 + -1x4 Combine like terms: x4 + -1x4 = 0 18 + -9x2 + -1x4 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -18 + 9x2 + x4 = 0 Move the constant term to the right: Add '18' to each side of the equation. -18 + 9x2 + 18 + x4 = 0 + 18 Reorder the terms: -18 + 18 + 9x2 + x4 = 0 + 18 Combine like terms: -18 + 18 = 0 0 + 9x2 + x4 = 0 + 18 9x2 + x4 = 0 + 18 Combine like terms: 0 + 18 = 18 9x2 + x4 = 18 The x term is 9x2. 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. 9x2 + 20.25 + x4 = 18 + 20.25 Reorder the terms: 20.25 + 9x2 + x4 = 18 + 20.25 Combine like terms: 18 + 20.25 = 38.25 20.25 + 9x2 + x4 = 38.25 Factor a perfect square on the left side: (x2 + 4.5)(x2 + 4.5) = 38.25 Calculate the square root of the right side: 6.184658438 Break this problem into two subproblems by setting (x2 + 4.5) equal to 6.184658438 and -6.184658438.Subproblem 1
x2 + 4.5 = 6.184658438 Simplifying x2 + 4.5 = 6.184658438 Reorder the terms: 4.5 + x2 = 6.184658438 Solving 4.5 + x2 = 6.184658438 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 + x2 = 6.184658438 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x2 = 6.184658438 + -4.5 x2 = 6.184658438 + -4.5 Combine like terms: 6.184658438 + -4.5 = 1.684658438 x2 = 1.684658438 Simplifying x2 = 1.684658438 Take the square root of each side: x = {-1.297943927, 1.297943927}Subproblem 2
x2 + 4.5 = -6.184658438 Simplifying x2 + 4.5 = -6.184658438 Reorder the terms: 4.5 + x2 = -6.184658438 Solving 4.5 + x2 = -6.184658438 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 + x2 = -6.184658438 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x2 = -6.184658438 + -4.5 x2 = -6.184658438 + -4.5 Combine like terms: -6.184658438 + -4.5 = -10.684658438 x2 = -10.684658438 Simplifying x2 = -10.684658438 Reorder the terms: 10.684658438 + x2 = -10.684658438 + 10.684658438 Combine like terms: -10.684658438 + 10.684658438 = 0.000000000 10.684658438 + x2 = 0.000000000 The solution to this equation could not be determined.This subproblem is being ignored because a solution could not be determined.
