Simplifying 7 = 2x(x + -3) Reorder the terms: 7 = 2x(-3 + x) 7 = (-3 * 2x + x * 2x) 7 = (-6x + 2x2) Solving 7 = -6x + 2x2 Solving for variable 'x'. Reorder the terms: 7 + 6x + -2x2 = -6x + 6x + 2x2 + -2x2 Combine like terms: -6x + 6x = 0 7 + 6x + -2x2 = 0 + 2x2 + -2x2 7 + 6x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 7 + 6x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -3.5 + -3x + x2 = 0 Move the constant term to the right: Add '3.5' to each side of the equation. -3.5 + -3x + 3.5 + x2 = 0 + 3.5 Reorder the terms: -3.5 + 3.5 + -3x + x2 = 0 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + -3x + x2 = 0 + 3.5 -3x + x2 = 0 + 3.5 Combine like terms: 0 + 3.5 = 3.5 -3x + x2 = 3.5 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 = 3.5 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 3.5 + 2.25 Combine like terms: 3.5 + 2.25 = 5.75 2.25 + -3x + x2 = 5.75 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 5.75 Calculate the square root of the right side: 2.397915762 Break this problem into two subproblems by setting (x + -1.5) equal to 2.397915762 and -2.397915762.Subproblem 1
x + -1.5 = 2.397915762 Simplifying x + -1.5 = 2.397915762 Reorder the terms: -1.5 + x = 2.397915762 Solving -1.5 + x = 2.397915762 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 = 2.397915762 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 2.397915762 + 1.5 x = 2.397915762 + 1.5 Combine like terms: 2.397915762 + 1.5 = 3.897915762 x = 3.897915762 Simplifying x = 3.897915762Subproblem 2
x + -1.5 = -2.397915762 Simplifying x + -1.5 = -2.397915762 Reorder the terms: -1.5 + x = -2.397915762 Solving -1.5 + x = -2.397915762 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 = -2.397915762 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -2.397915762 + 1.5 x = -2.397915762 + 1.5 Combine like terms: -2.397915762 + 1.5 = -0.897915762 x = -0.897915762 Simplifying x = -0.897915762Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.897915762, -0.897915762}
