Simplifying 3x2 + -9x = 7 Reorder the terms: -9x + 3x2 = 7 Solving -9x + 3x2 = 7 Solving for variable 'x'. Reorder the terms: -7 + -9x + 3x2 = 7 + -7 Combine like terms: 7 + -7 = 0 -7 + -9x + 3x2 = 0 Begin completing the square. Divide all terms by 3 the coefficient of the squared term: Divide each side by '3'. -2.333333333 + -3x + x2 = 0 Move the constant term to the right: Add '2.333333333' to each side of the equation. -2.333333333 + -3x + 2.333333333 + x2 = 0 + 2.333333333 Reorder the terms: -2.333333333 + 2.333333333 + -3x + x2 = 0 + 2.333333333 Combine like terms: -2.333333333 + 2.333333333 = 0.000000000 0.000000000 + -3x + x2 = 0 + 2.333333333 -3x + x2 = 0 + 2.333333333 Combine like terms: 0 + 2.333333333 = 2.333333333 -3x + x2 = 2.333333333 The x term is -3x. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3x + 2.25 + x2 = 2.333333333 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 2.333333333 + 2.25 Combine like terms: 2.333333333 + 2.25 = 4.583333333 2.25 + -3x + x2 = 4.583333333 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 4.583333333 Calculate the square root of the right side: 2.140872096 Break this problem into two subproblems by setting (x + -1.5) equal to 2.140872096 and -2.140872096.Subproblem 1
x + -1.5 = 2.140872096 Simplifying x + -1.5 = 2.140872096 Reorder the terms: -1.5 + x = 2.140872096 Solving -1.5 + x = 2.140872096 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = 2.140872096 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 2.140872096 + 1.5 x = 2.140872096 + 1.5 Combine like terms: 2.140872096 + 1.5 = 3.640872096 x = 3.640872096 Simplifying x = 3.640872096Subproblem 2
x + -1.5 = -2.140872096 Simplifying x + -1.5 = -2.140872096 Reorder the terms: -1.5 + x = -2.140872096 Solving -1.5 + x = -2.140872096 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + x = -2.140872096 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -2.140872096 + 1.5 x = -2.140872096 + 1.5 Combine like terms: -2.140872096 + 1.5 = -0.640872096 x = -0.640872096 Simplifying x = -0.640872096Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.640872096, -0.640872096}
