Simplifying 100 + 20x + x2 = 9900 Solving 100 + 20x + x2 = 9900 Solving for variable 'x'. Reorder the terms: 100 + -9900 + 20x + x2 = 9900 + -9900 Combine like terms: 100 + -9900 = -9800 -9800 + 20x + x2 = 9900 + -9900 Combine like terms: 9900 + -9900 = 0 -9800 + 20x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '9800' to each side of the equation. -9800 + 20x + 9800 + x2 = 0 + 9800 Reorder the terms: -9800 + 9800 + 20x + x2 = 0 + 9800 Combine like terms: -9800 + 9800 = 0 0 + 20x + x2 = 0 + 9800 20x + x2 = 0 + 9800 Combine like terms: 0 + 9800 = 9800 20x + x2 = 9800 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 = 9800 + 100 Reorder the terms: 100 + 20x + x2 = 9800 + 100 Combine like terms: 9800 + 100 = 9900 100 + 20x + x2 = 9900 Factor a perfect square on the left side: (x + 10)(x + 10) = 9900 Calculate the square root of the right side: 99.498743711 Break this problem into two subproblems by setting (x + 10) equal to 99.498743711 and -99.498743711.Subproblem 1
x + 10 = 99.498743711 Simplifying x + 10 = 99.498743711 Reorder the terms: 10 + x = 99.498743711 Solving 10 + x = 99.498743711 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 = 99.498743711 + -10 Combine like terms: 10 + -10 = 0 0 + x = 99.498743711 + -10 x = 99.498743711 + -10 Combine like terms: 99.498743711 + -10 = 89.498743711 x = 89.498743711 Simplifying x = 89.498743711Subproblem 2
x + 10 = -99.498743711 Simplifying x + 10 = -99.498743711 Reorder the terms: 10 + x = -99.498743711 Solving 10 + x = -99.498743711 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 = -99.498743711 + -10 Combine like terms: 10 + -10 = 0 0 + x = -99.498743711 + -10 x = -99.498743711 + -10 Combine like terms: -99.498743711 + -10 = -109.498743711 x = -109.498743711 Simplifying x = -109.498743711Solution
The solution to the problem is based on the solutions from the subproblems. x = {89.498743711, -109.498743711}
