Simplifying (2x + -1)(10x + 1) = 0 Reorder the terms: (-1 + 2x)(10x + 1) = 0 Reorder the terms: (-1 + 2x)(1 + 10x) = 0 Multiply (-1 + 2x) * (1 + 10x) (-1(1 + 10x) + 2x * (1 + 10x)) = 0 ((1 * -1 + 10x * -1) + 2x * (1 + 10x)) = 0 ((-1 + -10x) + 2x * (1 + 10x)) = 0 (-1 + -10x + (1 * 2x + 10x * 2x)) = 0 (-1 + -10x + (2x + 20x2)) = 0 Combine like terms: -10x + 2x = -8x (-1 + -8x + 20x2) = 0 Solving -1 + -8x + 20x2 = 0 Solving for variable 'x'. Factor a trinomial. (-1 + -10x)(1 + -2x) = 0Subproblem 1
Set the factor '(-1 + -10x)' equal to zero and attempt to solve: Simplifying -1 + -10x = 0 Solving -1 + -10x = 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 + -10x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -10x = 0 + 1 -10x = 0 + 1 Combine like terms: 0 + 1 = 1 -10x = 1 Divide each side by '-10'. x = -0.1 Simplifying x = -0.1Subproblem 2
Set the factor '(1 + -2x)' equal to zero and attempt to solve: Simplifying 1 + -2x = 0 Solving 1 + -2x = 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 + -2x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2x = 0 + -1 -2x = 0 + -1 Combine like terms: 0 + -1 = -1 -2x = -1 Divide each side by '-2'. x = 0.5 Simplifying x = 0.5Solution
x = {-0.1, 0.5}
