Simplifying 0 = 5x2 + -31x + 6 Reorder the terms: 0 = 6 + -31x + 5x2 Solving 0 = 6 + -31x + 5x2 Solving for variable 'x'. Combine like terms: 0 + -6 = -6 -6 + 31x + -5x2 = 6 + -31x + 5x2 + -6 + 31x + -5x2 Reorder the terms: -6 + 31x + -5x2 = 6 + -6 + -31x + 31x + 5x2 + -5x2 Combine like terms: 6 + -6 = 0 -6 + 31x + -5x2 = 0 + -31x + 31x + 5x2 + -5x2 -6 + 31x + -5x2 = -31x + 31x + 5x2 + -5x2 Combine like terms: -31x + 31x = 0 -6 + 31x + -5x2 = 0 + 5x2 + -5x2 -6 + 31x + -5x2 = 5x2 + -5x2 Combine like terms: 5x2 + -5x2 = 0 -6 + 31x + -5x2 = 0 Factor a trinomial. (-6 + x)(1 + -5x) = 0Subproblem 1
Set the factor '(-6 + x)' equal to zero and attempt to solve: Simplifying -6 + x = 0 Solving -6 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = 0 + 6 Combine like terms: -6 + 6 = 0 0 + x = 0 + 6 x = 0 + 6 Combine like terms: 0 + 6 = 6 x = 6 Simplifying x = 6Subproblem 2
Set the factor '(1 + -5x)' equal to zero and attempt to solve: Simplifying 1 + -5x = 0 Solving 1 + -5x = 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 + -5x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -5x = 0 + -1 -5x = 0 + -1 Combine like terms: 0 + -1 = -1 -5x = -1 Divide each side by '-5'. x = 0.2 Simplifying x = 0.2Solution
x = {6, 0.2}
