Simplifying 4x2 + 49x + 1 = 81x + 1 Reorder the terms: 1 + 49x + 4x2 = 81x + 1 Reorder the terms: 1 + 49x + 4x2 = 1 + 81x Add '-1' to each side of the equation. 1 + 49x + -1 + 4x2 = 1 + -1 + 81x Reorder the terms: 1 + -1 + 49x + 4x2 = 1 + -1 + 81x Combine like terms: 1 + -1 = 0 0 + 49x + 4x2 = 1 + -1 + 81x 49x + 4x2 = 1 + -1 + 81x Combine like terms: 1 + -1 = 0 49x + 4x2 = 0 + 81x 49x + 4x2 = 81x Solving 49x + 4x2 = 81x Solving for variable 'x'. Reorder the terms: 49x + -81x + 4x2 = 81x + -81x Combine like terms: 49x + -81x = -32x -32x + 4x2 = 81x + -81x Combine like terms: 81x + -81x = 0 -32x + 4x2 = 0 Factor out the Greatest Common Factor (GCF), '4x'. 4x(-8 + x) = 0 Ignore the factor 4.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 '(-8 + x)' equal to zero and attempt to solve: Simplifying -8 + x = 0 Solving -8 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '8' to each side of the equation. -8 + 8 + x = 0 + 8 Combine like terms: -8 + 8 = 0 0 + x = 0 + 8 x = 0 + 8 Combine like terms: 0 + 8 = 8 x = 8 Simplifying x = 8Solution
x = {0, 8}
