Simplifying 0 = 4x2 + -13x + 3 Reorder the terms: 0 = 3 + -13x + 4x2 Solving 0 = 3 + -13x + 4x2 Solving for variable 'x'. Combine like terms: 0 + -3 = -3 -3 + 13x + -4x2 = 3 + -13x + 4x2 + -3 + 13x + -4x2 Reorder the terms: -3 + 13x + -4x2 = 3 + -3 + -13x + 13x + 4x2 + -4x2 Combine like terms: 3 + -3 = 0 -3 + 13x + -4x2 = 0 + -13x + 13x + 4x2 + -4x2 -3 + 13x + -4x2 = -13x + 13x + 4x2 + -4x2 Combine like terms: -13x + 13x = 0 -3 + 13x + -4x2 = 0 + 4x2 + -4x2 -3 + 13x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 -3 + 13x + -4x2 = 0 Factor a trinomial. (-3 + x)(1 + -4x) = 0Subproblem 1
Set the factor '(-3 + x)' equal to zero and attempt to solve: Simplifying -3 + x = 0 Solving -3 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + x = 0 + 3 x = 0 + 3 Combine like terms: 0 + 3 = 3 x = 3 Simplifying x = 3Subproblem 2
Set the factor '(1 + -4x)' equal to zero and attempt to solve: Simplifying 1 + -4x = 0 Solving 1 + -4x = 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 + -4x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -4x = 0 + -1 -4x = 0 + -1 Combine like terms: 0 + -1 = -1 -4x = -1 Divide each side by '-4'. x = 0.25 Simplifying x = 0.25Solution
x = {3, 0.25}
