Simplifying x(10x + -21) = 0 Reorder the terms: x(-21 + 10x) = 0 (-21 * x + 10x * x) = 0 (-21x + 10x2) = 0 Solving -21x + 10x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(-21 + 10x) = 0Subproblem 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 '(-21 + 10x)' equal to zero and attempt to solve: Simplifying -21 + 10x = 0 Solving -21 + 10x = 0 Move all terms containing x to the left, all other terms to the right. Add '21' to each side of the equation. -21 + 21 + 10x = 0 + 21 Combine like terms: -21 + 21 = 0 0 + 10x = 0 + 21 10x = 0 + 21 Combine like terms: 0 + 21 = 21 10x = 21 Divide each side by '10'. x = 2.1 Simplifying x = 2.1Solution
x = {0, 2.1}
