Simplifying 4x2 + -1800 = x + 1800 Reorder the terms: -1800 + 4x2 = x + 1800 Reorder the terms: -1800 + 4x2 = 1800 + x Solving -1800 + 4x2 = 1800 + x Solving for variable 'x'. Reorder the terms: -1800 + -1800 + -1x + 4x2 = 1800 + x + -1800 + -1x Combine like terms: -1800 + -1800 = -3600 -3600 + -1x + 4x2 = 1800 + x + -1800 + -1x Reorder the terms: -3600 + -1x + 4x2 = 1800 + -1800 + x + -1x Combine like terms: 1800 + -1800 = 0 -3600 + -1x + 4x2 = 0 + x + -1x -3600 + -1x + 4x2 = x + -1x Combine like terms: x + -1x = 0 -3600 + -1x + 4x2 = 0 Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -900 + -0.25x + x2 = 0 Move the constant term to the right: Add '900' to each side of the equation. -900 + -0.25x + 900 + x2 = 0 + 900 Reorder the terms: -900 + 900 + -0.25x + x2 = 0 + 900 Combine like terms: -900 + 900 = 0 0 + -0.25x + x2 = 0 + 900 -0.25x + x2 = 0 + 900 Combine like terms: 0 + 900 = 900 -0.25x + x2 = 900 The x term is -0.25x. Take half its coefficient (-0.125). Square it (0.015625) and add it to both sides. Add '0.015625' to each side of the equation. -0.25x + 0.015625 + x2 = 900 + 0.015625 Reorder the terms: 0.015625 + -0.25x + x2 = 900 + 0.015625 Combine like terms: 900 + 0.015625 = 900.015625 0.015625 + -0.25x + x2 = 900.015625 Factor a perfect square on the left side: (x + -0.125)(x + -0.125) = 900.015625 Calculate the square root of the right side: 30.000260416 Break this problem into two subproblems by setting (x + -0.125) equal to 30.000260416 and -30.000260416.Subproblem 1
x + -0.125 = 30.000260416 Simplifying x + -0.125 = 30.000260416 Reorder the terms: -0.125 + x = 30.000260416 Solving -0.125 + x = 30.000260416 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + x = 30.000260416 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = 30.000260416 + 0.125 x = 30.000260416 + 0.125 Combine like terms: 30.000260416 + 0.125 = 30.125260416 x = 30.125260416 Simplifying x = 30.125260416Subproblem 2
x + -0.125 = -30.000260416 Simplifying x + -0.125 = -30.000260416 Reorder the terms: -0.125 + x = -30.000260416 Solving -0.125 + x = -30.000260416 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.125' to each side of the equation. -0.125 + 0.125 + x = -30.000260416 + 0.125 Combine like terms: -0.125 + 0.125 = 0.000 0.000 + x = -30.000260416 + 0.125 x = -30.000260416 + 0.125 Combine like terms: -30.000260416 + 0.125 = -29.875260416 x = -29.875260416 Simplifying x = -29.875260416Solution
