Simplifying x4 + 2x2 + 2 = 24 Reorder the terms: 2 + 2x2 + x4 = 24 Solving 2 + 2x2 + x4 = 24 Solving for variable 'x'. Reorder the terms: 2 + -24 + 2x2 + x4 = 24 + -24 Combine like terms: 2 + -24 = -22 -22 + 2x2 + x4 = 24 + -24 Combine like terms: 24 + -24 = 0 -22 + 2x2 + x4 = 0 Begin completing the square. Move the constant term to the right: Add '22' to each side of the equation. -22 + 2x2 + 22 + x4 = 0 + 22 Reorder the terms: -22 + 22 + 2x2 + x4 = 0 + 22 Combine like terms: -22 + 22 = 0 0 + 2x2 + x4 = 0 + 22 2x2 + x4 = 0 + 22 Combine like terms: 0 + 22 = 22 2x2 + x4 = 22 The x term is 2x2. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x2 + 1 + x4 = 22 + 1 Reorder the terms: 1 + 2x2 + x4 = 22 + 1 Combine like terms: 22 + 1 = 23 1 + 2x2 + x4 = 23 Factor a perfect square on the left side: (x2 + 1)(x2 + 1) = 23 Calculate the square root of the right side: 4.795831523 Break this problem into two subproblems by setting (x2 + 1) equal to 4.795831523 and -4.795831523.Subproblem 1
x2 + 1 = 4.795831523 Simplifying x2 + 1 = 4.795831523 Reorder the terms: 1 + x2 = 4.795831523 Solving 1 + x2 = 4.795831523 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x2 = 4.795831523 + -1 Combine like terms: 1 + -1 = 0 0 + x2 = 4.795831523 + -1 x2 = 4.795831523 + -1 Combine like terms: 4.795831523 + -1 = 3.795831523 x2 = 3.795831523 Simplifying x2 = 3.795831523 Take the square root of each side: x = {-1.948289384, 1.948289384}Subproblem 2
