Simplifying 5x4 + -20 = 160 Reorder the terms: -20 + 5x4 = 160 Solving -20 + 5x4 = 160 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '20' to each side of the equation. -20 + 20 + 5x4 = 160 + 20 Combine like terms: -20 + 20 = 0 0 + 5x4 = 160 + 20 5x4 = 160 + 20 Combine like terms: 160 + 20 = 180 5x4 = 180 Divide each side by '5'. x4 = 36 Simplifying x4 = 36 Reorder the terms: -36 + x4 = 36 + -36 Combine like terms: 36 + -36 = 0 -36 + x4 = 0 Factor a difference between two squares. (6 + x2)(-6 + x2) = 0Subproblem 1
Set the factor '(6 + x2)' equal to zero and attempt to solve: Simplifying 6 + x2 = 0 Solving 6 + x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + x2 = 0 + -6 Combine like terms: 6 + -6 = 0 0 + x2 = 0 + -6 x2 = 0 + -6 Combine like terms: 0 + -6 = -6 x2 = -6 Simplifying x2 = -6 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 '(-6 + x2)' equal to zero and attempt to solve: Simplifying -6 + x2 = 0 Solving -6 + x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x2 = 0 + 6 Combine like terms: -6 + 6 = 0 0 + x2 = 0 + 6 x2 = 0 + 6 Combine like terms: 0 + 6 = 6 x2 = 6 Simplifying x2 = 6 Take the square root of each side: x = {-2.449489743, 2.449489743}Solution
x = {-2.449489743, 2.449489743}
