Simplifying 3x2 + 5x + 6.25 = 4.25 Reorder the terms: 6.25 + 5x + 3x2 = 4.25 Solving 6.25 + 5x + 3x2 = 4.25 Solving for variable 'x'. Reorder the terms: 6.25 + -4.25 + 5x + 3x2 = 4.25 + -4.25 Combine like terms: 6.25 + -4.25 = 2 2 + 5x + 3x2 = 4.25 + -4.25 Combine like terms: 4.25 + -4.25 = 0.00 2 + 5x + 3x2 = 0.00 Factor a trinomial. (1 + x)(2 + 3x) = 0.00Subproblem 1
Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 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 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1Subproblem 2
Set the factor '(2 + 3x)' equal to zero and attempt to solve: Simplifying 2 + 3x = 0 Solving 2 + 3x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + 3x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 3x = 0 + -2 3x = 0 + -2 Combine like terms: 0 + -2 = -2 3x = -2 Divide each side by '3'. x = -0.6666666667 Simplifying x = -0.6666666667Solution
x = {-1, -0.6666666667}
