Simplifying 0 = x4 + -25 Reorder the terms: 0 = -25 + x4 Solving 0 = -25 + x4 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1x4' to each side of the equation. 0 + -1x4 = -25 + x4 + -1x4 Remove the zero: -1x4 = -25 + x4 + -1x4 Combine like terms: x4 + -1x4 = 0 -1x4 = -25 + 0 -1x4 = -25 Divide each side by '-1'. x4 = 25 Simplifying x4 = 25 Reorder the terms: -25 + x4 = 25 + -25 Combine like terms: 25 + -25 = 0 -25 + x4 = 0 Factor a difference between two squares. (5 + x2)(-5 + x2) = 0Subproblem 1
Set the factor '(5 + x2)' equal to zero and attempt to solve: Simplifying 5 + x2 = 0 Solving 5 + x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + x2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + x2 = 0 + -5 x2 = 0 + -5 Combine like terms: 0 + -5 = -5 x2 = -5 Simplifying x2 = -5 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(-5 + x2)' equal to zero and attempt to solve: Simplifying -5 + x2 = 0 Solving -5 + x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + x2 = 0 + 5 x2 = 0 + 5 Combine like terms: 0 + 5 = 5 x2 = 5 Simplifying x2 = 5 Take the square root of each side: x = {-2.236067978, 2.236067978}Solution
x = {-2.236067978, 2.236067978}
