Simplifying x(x + -10) = 12.5 Reorder the terms: x(-10 + x) = 12.5 (-10 * x + x * x) = 12.5 (-10x + x2) = 12.5 Solving -10x + x2 = 12.5 Solving for variable 'x'. Reorder the terms: -12.5 + -10x + x2 = 12.5 + -12.5 Combine like terms: 12.5 + -12.5 = 0.0 -12.5 + -10x + x2 = 0.0 Begin completing the square. Move the constant term to the right: Add '12.5' to each side of the equation. -12.5 + -10x + 12.5 + x2 = 0.0 + 12.5 Reorder the terms: -12.5 + 12.5 + -10x + x2 = 0.0 + 12.5 Combine like terms: -12.5 + 12.5 = 0.0 0.0 + -10x + x2 = 0.0 + 12.5 -10x + x2 = 0.0 + 12.5 Combine like terms: 0.0 + 12.5 = 12.5 -10x + x2 = 12.5 The x term is -10x. Take half its coefficient (-5). Square it (25) and add it to both sides. Add '25' to each side of the equation. -10x + 25 + x2 = 12.5 + 25 Reorder the terms: 25 + -10x + x2 = 12.5 + 25 Combine like terms: 12.5 + 25 = 37.5 25 + -10x + x2 = 37.5 Factor a perfect square on the left side: (x + -5)(x + -5) = 37.5 Calculate the square root of the right side: 6.123724357 Break this problem into two subproblems by setting (x + -5) equal to 6.123724357 and -6.123724357.Subproblem 1
x + -5 = 6.123724357 Simplifying x + -5 = 6.123724357 Reorder the terms: -5 + x = 6.123724357 Solving -5 + x = 6.123724357 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = 6.123724357 + 5 Combine like terms: -5 + 5 = 0 0 + x = 6.123724357 + 5 x = 6.123724357 + 5 Combine like terms: 6.123724357 + 5 = 11.123724357 x = 11.123724357 Simplifying x = 11.123724357Subproblem 2
x + -5 = -6.123724357 Simplifying x + -5 = -6.123724357 Reorder the terms: -5 + x = -6.123724357 Solving -5 + x = -6.123724357 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '5' to each side of the equation. -5 + 5 + x = -6.123724357 + 5 Combine like terms: -5 + 5 = 0 0 + x = -6.123724357 + 5 x = -6.123724357 + 5 Combine like terms: -6.123724357 + 5 = -1.123724357 x = -1.123724357 Simplifying x = -1.123724357Solution
