Simplifying -1.25x4 + 7.5x2 + -6.25 = 0 Reorder the terms: -6.25 + 7.5x2 + -1.25x4 = 0 Solving -6.25 + 7.5x2 + -1.25x4 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1.25 the coefficient of the squared term: Divide each side by '-1.25'. 5 + -6x2 + x4 = 0 Move the constant term to the right: Add '-5' to each side of the equation. 5 + -6x2 + -5 + x4 = 0 + -5 Reorder the terms: 5 + -5 + -6x2 + x4 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -6x2 + x4 = 0 + -5 -6x2 + x4 = 0 + -5 Combine like terms: 0 + -5 = -5 -6x2 + x4 = -5 The x term is -6x2. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x2 + 9 + x4 = -5 + 9 Reorder the terms: 9 + -6x2 + x4 = -5 + 9 Combine like terms: -5 + 9 = 4 9 + -6x2 + x4 = 4 Factor a perfect square on the left side: (x2 + -3)(x2 + -3) = 4 Calculate the square root of the right side: 2 Break this problem into two subproblems by setting (x2 + -3) equal to 2 and -2.Subproblem 1
x2 + -3 = 2 Simplifying x2 + -3 = 2 Reorder the terms: -3 + x2 = 2 Solving -3 + x2 = 2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x2 = 2 + 3 Combine like terms: -3 + 3 = 0 0 + x2 = 2 + 3 x2 = 2 + 3 Combine like terms: 2 + 3 = 5 x2 = 5 Simplifying x2 = 5 Take the square root of each side: x = {-2.236067978, 2.236067978}Subproblem 2
x2 + -3 = -2 Simplifying x2 + -3 = -2 Reorder the terms: -3 + x2 = -2 Solving -3 + x2 = -2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x2 = -2 + 3 Combine like terms: -3 + 3 = 0 0 + x2 = -2 + 3 x2 = -2 + 3 Combine like terms: -2 + 3 = 1 x2 = 1 Simplifying x2 = 1 Take the square root of each side: x = {-1, 1}Solution
The solution to the problem is based on the solutions from the subproblems. x = {-2.236067978, 2.236067978, -1, 1}
