Simplifying 2x4 + 5x2 = 1 Reorder the terms: 5x2 + 2x4 = 1 Solving 5x2 + 2x4 = 1 Solving for variable 'x'. Reorder the terms: -1 + 5x2 + 2x4 = 1 + -1 Combine like terms: 1 + -1 = 0 -1 + 5x2 + 2x4 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -0.5 + 2.5x2 + x4 = 0 Move the constant term to the right: Add '0.5' to each side of the equation. -0.5 + 2.5x2 + 0.5 + x4 = 0 + 0.5 Reorder the terms: -0.5 + 0.5 + 2.5x2 + x4 = 0 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + 2.5x2 + x4 = 0 + 0.5 2.5x2 + x4 = 0 + 0.5 Combine like terms: 0 + 0.5 = 0.5 2.5x2 + x4 = 0.5 The x term is 2.5x2. Take half its coefficient (1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. 2.5x2 + 1.5625 + x4 = 0.5 + 1.5625 Reorder the terms: 1.5625 + 2.5x2 + x4 = 0.5 + 1.5625 Combine like terms: 0.5 + 1.5625 = 2.0625 1.5625 + 2.5x2 + x4 = 2.0625 Factor a perfect square on the left side: (x2 + 1.25)(x2 + 1.25) = 2.0625 Calculate the square root of the right side: 1.436140662 Break this problem into two subproblems by setting (x2 + 1.25) equal to 1.436140662 and -1.436140662.Subproblem 1
