Simplifying x2 = 1.5x + 7 Reorder the terms: x2 = 7 + 1.5x Solving x2 = 7 + 1.5x Solving for variable 'x'. Reorder the terms: -7 + -1.5x + x2 = 7 + 1.5x + -7 + -1.5x Reorder the terms: -7 + -1.5x + x2 = 7 + -7 + 1.5x + -1.5x Combine like terms: 7 + -7 = 0 -7 + -1.5x + x2 = 0 + 1.5x + -1.5x -7 + -1.5x + x2 = 1.5x + -1.5x Combine like terms: 1.5x + -1.5x = 0.0 -7 + -1.5x + x2 = 0.0 Begin completing the square. Move the constant term to the right: Add '7' to each side of the equation. -7 + -1.5x + 7 + x2 = 0.0 + 7 Reorder the terms: -7 + 7 + -1.5x + x2 = 0.0 + 7 Combine like terms: -7 + 7 = 0 0 + -1.5x + x2 = 0.0 + 7 -1.5x + x2 = 0.0 + 7 Combine like terms: 0.0 + 7 = 7 -1.5x + x2 = 7 The x term is -1.5x. Take half its coefficient (-0.75). Square it (0.5625) and add it to both sides. Add '0.5625' to each side of the equation. -1.5x + 0.5625 + x2 = 7 + 0.5625 Reorder the terms: 0.5625 + -1.5x + x2 = 7 + 0.5625 Combine like terms: 7 + 0.5625 = 7.5625 0.5625 + -1.5x + x2 = 7.5625 Factor a perfect square on the left side: (x + -0.75)(x + -0.75) = 7.5625 Calculate the square root of the right side: 2.75 Break this problem into two subproblems by setting (x + -0.75) equal to 2.75 and -2.75.Subproblem 1
x + -0.75 = 2.75 Simplifying x + -0.75 = 2.75 Reorder the terms: -0.75 + x = 2.75 Solving -0.75 + x = 2.75 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = 2.75 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = 2.75 + 0.75 x = 2.75 + 0.75 Combine like terms: 2.75 + 0.75 = 3.5 x = 3.5 Simplifying x = 3.5Subproblem 2
x + -0.75 = -2.75 Simplifying x + -0.75 = -2.75 Reorder the terms: -0.75 + x = -2.75 Solving -0.75 + x = -2.75 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.75' to each side of the equation. -0.75 + 0.75 + x = -2.75 + 0.75 Combine like terms: -0.75 + 0.75 = 0.00 0.00 + x = -2.75 + 0.75 x = -2.75 + 0.75 Combine like terms: -2.75 + 0.75 = -2 x = -2 Simplifying x = -2Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.5, -2}
