Simplifying x2 + -5x = 2x + 3 Reorder the terms: -5x + x2 = 2x + 3 Reorder the terms: -5x + x2 = 3 + 2x Solving -5x + x2 = 3 + 2x Solving for variable 'x'. Reorder the terms: -3 + -5x + -2x + x2 = 3 + 2x + -3 + -2x Combine like terms: -5x + -2x = -7x -3 + -7x + x2 = 3 + 2x + -3 + -2x Reorder the terms: -3 + -7x + x2 = 3 + -3 + 2x + -2x Combine like terms: 3 + -3 = 0 -3 + -7x + x2 = 0 + 2x + -2x -3 + -7x + x2 = 2x + -2x Combine like terms: 2x + -2x = 0 -3 + -7x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '3' to each side of the equation. -3 + -7x + 3 + x2 = 0 + 3 Reorder the terms: -3 + 3 + -7x + x2 = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -7x + x2 = 0 + 3 -7x + x2 = 0 + 3 Combine like terms: 0 + 3 = 3 -7x + x2 = 3 The x term is -7x. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7x + 12.25 + x2 = 3 + 12.25 Reorder the terms: 12.25 + -7x + x2 = 3 + 12.25 Combine like terms: 3 + 12.25 = 15.25 12.25 + -7x + x2 = 15.25 Factor a perfect square on the left side: (x + -3.5)(x + -3.5) = 15.25 Calculate the square root of the right side: 3.905124838 Break this problem into two subproblems by setting (x + -3.5) equal to 3.905124838 and -3.905124838.Subproblem 1
x + -3.5 = 3.905124838 Simplifying x + -3.5 = 3.905124838 Reorder the terms: -3.5 + x = 3.905124838 Solving -3.5 + x = 3.905124838 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + x = 3.905124838 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = 3.905124838 + 3.5 x = 3.905124838 + 3.5 Combine like terms: 3.905124838 + 3.5 = 7.405124838 x = 7.405124838 Simplifying x = 7.405124838Subproblem 2
x + -3.5 = -3.905124838 Simplifying x + -3.5 = -3.905124838 Reorder the terms: -3.5 + x = -3.905124838 Solving -3.5 + x = -3.905124838 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + x = -3.905124838 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + x = -3.905124838 + 3.5 x = -3.905124838 + 3.5 Combine like terms: -3.905124838 + 3.5 = -0.405124838 x = -0.405124838 Simplifying x = -0.405124838Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.405124838, -0.405124838}
