Simplifying 4x4 + -16x2 + 9 = 0 Reorder the terms: 9 + -16x2 + 4x4 = 0 Solving 9 + -16x2 + 4x4 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. 2.25 + -4x2 + x4 = 0 Move the constant term to the right: Add '-2.25' to each side of the equation. 2.25 + -4x2 + -2.25 + x4 = 0 + -2.25 Reorder the terms: 2.25 + -2.25 + -4x2 + x4 = 0 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + -4x2 + x4 = 0 + -2.25 -4x2 + x4 = 0 + -2.25 Combine like terms: 0 + -2.25 = -2.25 -4x2 + x4 = -2.25 The x term is -4x2. Take half its coefficient (-2). Square it (4) and add it to both sides. Add '4' to each side of the equation. -4x2 + 4 + x4 = -2.25 + 4 Reorder the terms: 4 + -4x2 + x4 = -2.25 + 4 Combine like terms: -2.25 + 4 = 1.75 4 + -4x2 + x4 = 1.75 Factor a perfect square on the left side: (x2 + -2)(x2 + -2) = 1.75 Calculate the square root of the right side: 1.322875656 Break this problem into two subproblems by setting (x2 + -2) equal to 1.322875656 and -1.322875656.Subproblem 1
x2 + -2 = 1.322875656 Simplifying x2 + -2 = 1.322875656 Reorder the terms: -2 + x2 = 1.322875656 Solving -2 + x2 = 1.322875656 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x2 = 1.322875656 + 2 Combine like terms: -2 + 2 = 0 0 + x2 = 1.322875656 + 2 x2 = 1.322875656 + 2 Combine like terms: 1.322875656 + 2 = 3.322875656 x2 = 3.322875656 Simplifying x2 = 3.322875656 Take the square root of each side: x = {-1.822875656, 1.822875656}Subproblem 2
x2 + -2 = -1.322875656 Simplifying x2 + -2 = -1.322875656 Reorder the terms: -2 + x2 = -1.322875656 Solving -2 + x2 = -1.322875656 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + x2 = -1.322875656 + 2 Combine like terms: -2 + 2 = 0 0 + x2 = -1.322875656 + 2 x2 = -1.322875656 + 2 Combine like terms: -1.322875656 + 2 = 0.677124344 x2 = 0.677124344 Simplifying x2 = 0.677124344 Take the square root of each side: x = {-0.822875655, 0.822875655}Solution
