Simplifying 9x4 + -28 = -59x2 Reorder the terms: -28 + 9x4 = -59x2 Solving -28 + 9x4 = -59x2 Solving for variable 'x'. Reorder the terms: -28 + 59x2 + 9x4 = -59x2 + 59x2 Combine like terms: -59x2 + 59x2 = 0 -28 + 59x2 + 9x4 = 0 Factor a trinomial. (-7 + -1x2)(4 + -9x2) = 0 Factor a difference between two squares. (-7 + -1x2)((2 + 3x)(2 + -3x)) = 0Subproblem 1
Set the factor '(-7 + -1x2)' equal to zero and attempt to solve: Simplifying -7 + -1x2 = 0 Solving -7 + -1x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + -1x2 = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -1x2 = 0 + 7 -1x2 = 0 + 7 Combine like terms: 0 + 7 = 7 -1x2 = 7 Divide each side by '-1'. x2 = -7 Simplifying x2 = -7 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 '(2 + 3x)' equal to zero and attempt to solve: Simplifying 2 + 3x = 0 Solving 2 + 3x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + 3x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 3x = 0 + -2 3x = 0 + -2 Combine like terms: 0 + -2 = -2 3x = -2 Divide each side by '3'. x = -0.6666666667 Simplifying x = -0.6666666667Subproblem 3
Set the factor '(2 + -3x)' equal to zero and attempt to solve: Simplifying 2 + -3x = 0 Solving 2 + -3x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -3x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -3x = 0 + -2 -3x = 0 + -2 Combine like terms: 0 + -2 = -2 -3x = -2 Divide each side by '-3'. x = 0.6666666667 Simplifying x = 0.6666666667Solution
x = {-0.6666666667, 0.6666666667}
