Simplifying 5x4 + -15x2 + -4 = 0 Reorder the terms: -4 + -15x2 + 5x4 = 0 Solving -4 + -15x2 + 5x4 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -0.8 + -3x2 + x4 = 0 Move the constant term to the right: Add '0.8' to each side of the equation. -0.8 + -3x2 + 0.8 + x4 = 0 + 0.8 Reorder the terms: -0.8 + 0.8 + -3x2 + x4 = 0 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + -3x2 + x4 = 0 + 0.8 -3x2 + x4 = 0 + 0.8 Combine like terms: 0 + 0.8 = 0.8 -3x2 + x4 = 0.8 The x term is -3x2. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x2 + 2.25 + x4 = 0.8 + 2.25 Reorder the terms: 2.25 + -3x2 + x4 = 0.8 + 2.25 Combine like terms: 0.8 + 2.25 = 3.05 2.25 + -3x2 + x4 = 3.05 Factor a perfect square on the left side: (x2 + -1.5)(x2 + -1.5) = 3.05 Calculate the square root of the right side: 1.74642492 Break this problem into two subproblems by setting (x2 + -1.5) equal to 1.74642492 and -1.74642492.Subproblem 1
x2 + -1.5 = 1.74642492 Simplifying x2 + -1.5 = 1.74642492 Reorder the terms: -1.5 + x2 = 1.74642492 Solving -1.5 + x2 = 1.74642492 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x2 = 1.74642492 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x2 = 1.74642492 + 1.5 x2 = 1.74642492 + 1.5 Combine like terms: 1.74642492 + 1.5 = 3.24642492 x2 = 3.24642492 Simplifying x2 = 3.24642492 Take the square root of each side: x = {-1.801783816, 1.801783816}Subproblem 2
