Simplifying 42x3 + 49x = 0 Reorder the terms: 49x + 42x3 = 0 Solving 49x + 42x3 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '7x'. 7x(7 + 6x2) = 0 Ignore the factor 7.Subproblem 1
Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0Subproblem 2
Set the factor '(7 + 6x2)' equal to zero and attempt to solve: Simplifying 7 + 6x2 = 0 Solving 7 + 6x2 = 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 + 6x2 = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 6x2 = 0 + -7 6x2 = 0 + -7 Combine like terms: 0 + -7 = -7 6x2 = -7 Divide each side by '6'. x2 = -1.166666667 Simplifying x2 = -1.166666667 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
