Simplifying x2 + 20x + -1800 = 0 Reorder the terms: -1800 + 20x + x2 = 0 Solving -1800 + 20x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '1800' to each side of the equation. -1800 + 20x + 1800 + x2 = 0 + 1800 Reorder the terms: -1800 + 1800 + 20x + x2 = 0 + 1800 Combine like terms: -1800 + 1800 = 0 0 + 20x + x2 = 0 + 1800 20x + x2 = 0 + 1800 Combine like terms: 0 + 1800 = 1800 20x + x2 = 1800 The x term is 20x. Take half its coefficient (10). Square it (100) and add it to both sides. Add '100' to each side of the equation. 20x + 100 + x2 = 1800 + 100 Reorder the terms: 100 + 20x + x2 = 1800 + 100 Combine like terms: 1800 + 100 = 1900 100 + 20x + x2 = 1900 Factor a perfect square on the left side: (x + 10)(x + 10) = 1900 Calculate the square root of the right side: 43.588989435 Break this problem into two subproblems by setting (x + 10) equal to 43.588989435 and -43.588989435.Subproblem 1
x + 10 = 43.588989435 Simplifying x + 10 = 43.588989435 Reorder the terms: 10 + x = 43.588989435 Solving 10 + x = 43.588989435 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = 43.588989435 + -10 Combine like terms: 10 + -10 = 0 0 + x = 43.588989435 + -10 x = 43.588989435 + -10 Combine like terms: 43.588989435 + -10 = 33.588989435 x = 33.588989435 Simplifying x = 33.588989435Subproblem 2
x + 10 = -43.588989435 Simplifying x + 10 = -43.588989435 Reorder the terms: 10 + x = -43.588989435 Solving 10 + x = -43.588989435 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = -43.588989435 + -10 Combine like terms: 10 + -10 = 0 0 + x = -43.588989435 + -10 x = -43.588989435 + -10 Combine like terms: -43.588989435 + -10 = -53.588989435 x = -53.588989435 Simplifying x = -53.588989435Solution
The solution to the problem is based on the solutions from the subproblems. x = {33.588989435, -53.588989435}
