Simplifying 2x4 + -15x2 + 12 = 0 Reorder the terms: 12 + -15x2 + 2x4 = 0 Solving 12 + -15x2 + 2x4 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 6 + -7.5x2 + x4 = 0 Move the constant term to the right: Add '-6' to each side of the equation. 6 + -7.5x2 + -6 + x4 = 0 + -6 Reorder the terms: 6 + -6 + -7.5x2 + x4 = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -7.5x2 + x4 = 0 + -6 -7.5x2 + x4 = 0 + -6 Combine like terms: 0 + -6 = -6 -7.5x2 + x4 = -6 The x term is -7.5x2. Take half its coefficient (-3.75). Square it (14.0625) and add it to both sides. Add '14.0625' to each side of the equation. -7.5x2 + 14.0625 + x4 = -6 + 14.0625 Reorder the terms: 14.0625 + -7.5x2 + x4 = -6 + 14.0625 Combine like terms: -6 + 14.0625 = 8.0625 14.0625 + -7.5x2 + x4 = 8.0625 Factor a perfect square on the left side: (x2 + -3.75)(x2 + -3.75) = 8.0625 Calculate the square root of the right side: 2.839454173 Break this problem into two subproblems by setting (x2 + -3.75) equal to 2.839454173 and -2.839454173.Subproblem 1
