Simplifying 15x4 + -15x2 = 18 Reorder the terms: -15x2 + 15x4 = 18 Solving -15x2 + 15x4 = 18 Solving for variable 'x'. Reorder the terms: -18 + -15x2 + 15x4 = 18 + -18 Combine like terms: 18 + -18 = 0 -18 + -15x2 + 15x4 = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(-6 + -5x2 + 5x4) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-6 + -5x2 + 5x4)' equal to zero and attempt to solve: Simplifying -6 + -5x2 + 5x4 = 0 Solving -6 + -5x2 + 5x4 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -1.2 + -1x2 + x4 = 0 Move the constant term to the right: Add '1.2' to each side of the equation. -1.2 + -1x2 + 1.2 + x4 = 0 + 1.2 Reorder the terms: -1.2 + 1.2 + -1x2 + x4 = 0 + 1.2 Combine like terms: -1.2 + 1.2 = 0.0 0.0 + -1x2 + x4 = 0 + 1.2 -1x2 + x4 = 0 + 1.2 Combine like terms: 0 + 1.2 = 1.2 -1x2 + x4 = 1.2 The x term is -1x2. Take half its coefficient (-0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. -1x2 + 0.25 + x4 = 1.2 + 0.25 Reorder the terms: 0.25 + -1x2 + x4 = 1.2 + 0.25 Combine like terms: 1.2 + 0.25 = 1.45 0.25 + -1x2 + x4 = 1.45 Factor a perfect square on the left side: (x2 + -0.5)(x2 + -0.5) = 1.45 Calculate the square root of the right side: 1.204159458 Break this problem into two subproblems by setting (x2 + -0.5) equal to 1.204159458 and -1.204159458.Subproblem 1
