Simplifying 49x2 + -7x2 = 42x Combine like terms: 49x2 + -7x2 = 42x2 42x2 = 42x Solving 42x2 = 42x Solving for variable 'x'. Reorder the terms: -42x + 42x2 = 42x + -42x Combine like terms: 42x + -42x = 0 -42x + 42x2 = 0 Factor out the Greatest Common Factor (GCF), '42x'. 42x(-1 + x) = 0 Ignore the factor 42.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 '(-1 + x)' equal to zero and attempt to solve: Simplifying -1 + x = 0 Solving -1 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + x = 0 + 1 x = 0 + 1 Combine like terms: 0 + 1 = 1 x = 1 Simplifying x = 1Solution
x = {0, 1}
