Simplifying 7 = 3x + 2x2 Solving 7 = 3x + 2x2 Solving for variable 'x'. Reorder the terms: 7 + -3x + -2x2 = 3x + -3x + 2x2 + -2x2 Combine like terms: 3x + -3x = 0 7 + -3x + -2x2 = 0 + 2x2 + -2x2 7 + -3x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 7 + -3x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -3.5 + 1.5x + x2 = 0 Move the constant term to the right: Add '3.5' to each side of the equation. -3.5 + 1.5x + 3.5 + x2 = 0 + 3.5 Reorder the terms: -3.5 + 3.5 + 1.5x + x2 = 0 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + 1.5x + x2 = 0 + 3.5 1.5x + x2 = 0 + 3.5 Combine like terms: 0 + 3.5 = 3.5 1.5x + x2 = 3.5 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 = 3.5 + 0.5625 Reorder the terms: 0.5625 + 1.5x + x2 = 3.5 + 0.5625 Combine like terms: 3.5 + 0.5625 = 4.0625 0.5625 + 1.5x + x2 = 4.0625 Factor a perfect square on the left side: (x + 0.75)(x + 0.75) = 4.0625 Calculate the square root of the right side: 2.015564437 Break this problem into two subproblems by setting (x + 0.75) equal to 2.015564437 and -2.015564437.Subproblem 1
x + 0.75 = 2.015564437 Simplifying x + 0.75 = 2.015564437 Reorder the terms: 0.75 + x = 2.015564437 Solving 0.75 + x = 2.015564437 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 = 2.015564437 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = 2.015564437 + -0.75 x = 2.015564437 + -0.75 Combine like terms: 2.015564437 + -0.75 = 1.265564437 x = 1.265564437 Simplifying x = 1.265564437Subproblem 2
x + 0.75 = -2.015564437 Simplifying x + 0.75 = -2.015564437 Reorder the terms: 0.75 + x = -2.015564437 Solving 0.75 + x = -2.015564437 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 = -2.015564437 + -0.75 Combine like terms: 0.75 + -0.75 = 0.00 0.00 + x = -2.015564437 + -0.75 x = -2.015564437 + -0.75 Combine like terms: -2.015564437 + -0.75 = -2.765564437 x = -2.765564437 Simplifying x = -2.765564437Solution
