Simplifying x4 + 51x2 + -4900 = 0 Reorder the terms: -4900 + 51x2 + x4 = 0 Solving -4900 + 51x2 + x4 = 0 Solving for variable 'x'. Factor a trinomial. (-100 + -1x2)(49 + -1x2) = 0 Factor a difference between two squares. (-100 + -1x2)((7 + x)(7 + -1x)) = 0Subproblem 1
Set the factor '(-100 + -1x2)' equal to zero and attempt to solve: Simplifying -100 + -1x2 = 0 Solving -100 + -1x2 = 0 Move all terms containing x to the left, all other terms to the right. Add '100' to each side of the equation. -100 + 100 + -1x2 = 0 + 100 Combine like terms: -100 + 100 = 0 0 + -1x2 = 0 + 100 -1x2 = 0 + 100 Combine like terms: 0 + 100 = 100 -1x2 = 100 Divide each side by '-1'. x2 = -100 Simplifying x2 = -100 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 '(7 + x)' equal to zero and attempt to solve: Simplifying 7 + x = 0 Solving 7 + x = 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 + x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + x = 0 + -7 x = 0 + -7 Combine like terms: 0 + -7 = -7 x = -7 Simplifying x = -7Subproblem 3
Set the factor '(7 + -1x)' equal to zero and attempt to solve: Simplifying 7 + -1x = 0 Solving 7 + -1x = 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 + -1x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1x = 0 + -7 -1x = 0 + -7 Combine like terms: 0 + -7 = -7 -1x = -7 Divide each side by '-1'. x = 7 Simplifying x = 7Solution
x = {-7, 7}
