Simplifying 21x2 + -49x5 = 0 Solving 21x2 + -49x5 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '7x2'. 7x2(3 + -7x3) = 0 Ignore the factor 7.Subproblem 1
Set the factor 'x2' equal to zero and attempt to solve: Simplifying x2 = 0 Solving x2 = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x2 = 0 Take the square root of each side: x = {0}Subproblem 2
Set the factor '(3 + -7x3)' equal to zero and attempt to solve: Simplifying 3 + -7x3 = 0 Solving 3 + -7x3 = 0 Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -7x3 = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -7x3 = 0 + -3 -7x3 = 0 + -3 Combine like terms: 0 + -3 = -3 -7x3 = -3 Divide each side by '-7'. x3 = 0.4285714286 Simplifying x3 = 0.4285714286 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
