Simplifying 3x2 = 15x + 2 Reorder the terms: 3x2 = 2 + 15x Solving 3x2 = 2 + 15x Solving for variable 'x'. Reorder the terms: -2 + -15x + 3x2 = 2 + 15x + -2 + -15x Reorder the terms: -2 + -15x + 3x2 = 2 + -2 + 15x + -15x Combine like terms: 2 + -2 = 0 -2 + -15x + 3x2 = 0 + 15x + -15x -2 + -15x + 3x2 = 15x + -15x Combine like terms: 15x + -15x = 0 -2 + -15x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -0.6666666667 + -5x + x2 = 0 Move the constant term to the right: Add '0.6666666667' to each side of the equation. -0.6666666667 + -5x + 0.6666666667 + x2 = 0 + 0.6666666667 Reorder the terms: -0.6666666667 + 0.6666666667 + -5x + x2 = 0 + 0.6666666667 Combine like terms: -0.6666666667 + 0.6666666667 = 0.0000000000 0.0000000000 + -5x + x2 = 0 + 0.6666666667 -5x + x2 = 0 + 0.6666666667 Combine like terms: 0 + 0.6666666667 = 0.6666666667 -5x + x2 = 0.6666666667 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = 0.6666666667 + 6.25 Reorder the terms: 6.25 + -5x + x2 = 0.6666666667 + 6.25 Combine like terms: 0.6666666667 + 6.25 = 6.9166666667 6.25 + -5x + x2 = 6.9166666667 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 6.9166666667 Calculate the square root of the right side: 2.62995564 Break this problem into two subproblems by setting (x + -2.5) equal to 2.62995564 and -2.62995564.Subproblem 1
x + -2.5 = 2.62995564 Simplifying x + -2.5 = 2.62995564 Reorder the terms: -2.5 + x = 2.62995564 Solving -2.5 + x = 2.62995564 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 2.62995564 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 2.62995564 + 2.5 x = 2.62995564 + 2.5 Combine like terms: 2.62995564 + 2.5 = 5.12995564 x = 5.12995564 Simplifying x = 5.12995564Subproblem 2
x + -2.5 = -2.62995564 Simplifying x + -2.5 = -2.62995564 Reorder the terms: -2.5 + x = -2.62995564 Solving -2.5 + x = -2.62995564 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -2.62995564 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -2.62995564 + 2.5 x = -2.62995564 + 2.5 Combine like terms: -2.62995564 + 2.5 = -0.12995564 x = -0.12995564 Simplifying x = -0.12995564Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.12995564, -0.12995564}
