Simplifying x2 + 25x = 196 Reorder the terms: 25x + x2 = 196 Solving 25x + x2 = 196 Solving for variable 'x'. Reorder the terms: -196 + 25x + x2 = 196 + -196 Combine like terms: 196 + -196 = 0 -196 + 25x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '196' to each side of the equation. -196 + 25x + 196 + x2 = 0 + 196 Reorder the terms: -196 + 196 + 25x + x2 = 0 + 196 Combine like terms: -196 + 196 = 0 0 + 25x + x2 = 0 + 196 25x + x2 = 0 + 196 Combine like terms: 0 + 196 = 196 25x + x2 = 196 The x term is 25x. Take half its coefficient (12.5). Square it (156.25) and add it to both sides. Add '156.25' to each side of the equation. 25x + 156.25 + x2 = 196 + 156.25 Reorder the terms: 156.25 + 25x + x2 = 196 + 156.25 Combine like terms: 196 + 156.25 = 352.25 156.25 + 25x + x2 = 352.25 Factor a perfect square on the left side: (x + 12.5)(x + 12.5) = 352.25 Calculate the square root of the right side: 18.768324379 Break this problem into two subproblems by setting (x + 12.5) equal to 18.768324379 and -18.768324379.Subproblem 1
x + 12.5 = 18.768324379 Simplifying x + 12.5 = 18.768324379 Reorder the terms: 12.5 + x = 18.768324379 Solving 12.5 + x = 18.768324379 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12.5' to each side of the equation. 12.5 + -12.5 + x = 18.768324379 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + x = 18.768324379 + -12.5 x = 18.768324379 + -12.5 Combine like terms: 18.768324379 + -12.5 = 6.268324379 x = 6.268324379 Simplifying x = 6.268324379Subproblem 2
x + 12.5 = -18.768324379 Simplifying x + 12.5 = -18.768324379 Reorder the terms: 12.5 + x = -18.768324379 Solving 12.5 + x = -18.768324379 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-12.5' to each side of the equation. 12.5 + -12.5 + x = -18.768324379 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 0.0 + x = -18.768324379 + -12.5 x = -18.768324379 + -12.5 Combine like terms: -18.768324379 + -12.5 = -31.268324379 x = -31.268324379 Simplifying x = -31.268324379Solution
