Simplifying x2 + -20x = 16 Reorder the terms: -20x + x2 = 16 Solving -20x + x2 = 16 Solving for variable 'x'. Reorder the terms: -16 + -20x + x2 = 16 + -16 Combine like terms: 16 + -16 = 0 -16 + -20x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '16' to each side of the equation. -16 + -20x + 16 + x2 = 0 + 16 Reorder the terms: -16 + 16 + -20x + x2 = 0 + 16 Combine like terms: -16 + 16 = 0 0 + -20x + x2 = 0 + 16 -20x + x2 = 0 + 16 Combine like terms: 0 + 16 = 16 -20x + x2 = 16 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 = 16 + 100 Reorder the terms: 100 + -20x + x2 = 16 + 100 Combine like terms: 16 + 100 = 116 100 + -20x + x2 = 116 Factor a perfect square on the left side: (x + -10)(x + -10) = 116 Calculate the square root of the right side: 10.770329614 Break this problem into two subproblems by setting (x + -10) equal to 10.770329614 and -10.770329614.Subproblem 1
x + -10 = 10.770329614 Simplifying x + -10 = 10.770329614 Reorder the terms: -10 + x = 10.770329614 Solving -10 + x = 10.770329614 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 = 10.770329614 + 10 Combine like terms: -10 + 10 = 0 0 + x = 10.770329614 + 10 x = 10.770329614 + 10 Combine like terms: 10.770329614 + 10 = 20.770329614 x = 20.770329614 Simplifying x = 20.770329614Subproblem 2
x + -10 = -10.770329614 Simplifying x + -10 = -10.770329614 Reorder the terms: -10 + x = -10.770329614 Solving -10 + x = -10.770329614 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 = -10.770329614 + 10 Combine like terms: -10 + 10 = 0 0 + x = -10.770329614 + 10 x = -10.770329614 + 10 Combine like terms: -10.770329614 + 10 = -0.770329614 x = -0.770329614 Simplifying x = -0.770329614Solution
