Simplifying 100x2 + 50x + 1 = 0 Reorder the terms: 1 + 50x + 100x2 = 0 Solving 1 + 50x + 100x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 100 the coefficient of the squared term: Divide each side by '100'. 0.01 + 0.5x + x2 = 0 Move the constant term to the right: Add '-0.01' to each side of the equation. 0.01 + 0.5x + -0.01 + x2 = 0 + -0.01 Reorder the terms: 0.01 + -0.01 + 0.5x + x2 = 0 + -0.01 Combine like terms: 0.01 + -0.01 = 0.00 0.00 + 0.5x + x2 = 0 + -0.01 0.5x + x2 = 0 + -0.01 Combine like terms: 0 + -0.01 = -0.01 0.5x + x2 = -0.01 The x term is 0.5x. Take half its coefficient (0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. 0.5x + 0.0625 + x2 = -0.01 + 0.0625 Reorder the terms: 0.0625 + 0.5x + x2 = -0.01 + 0.0625 Combine like terms: -0.01 + 0.0625 = 0.0525 0.0625 + 0.5x + x2 = 0.0525 Factor a perfect square on the left side: (x + 0.25)(x + 0.25) = 0.0525 Calculate the square root of the right side: 0.229128785 Break this problem into two subproblems by setting (x + 0.25) equal to 0.229128785 and -0.229128785.Subproblem 1
x + 0.25 = 0.229128785 Simplifying x + 0.25 = 0.229128785 Reorder the terms: 0.25 + x = 0.229128785 Solving 0.25 + x = 0.229128785 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + x = 0.229128785 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + x = 0.229128785 + -0.25 x = 0.229128785 + -0.25 Combine like terms: 0.229128785 + -0.25 = -0.020871215 x = -0.020871215 Simplifying x = -0.020871215Subproblem 2
x + 0.25 = -0.229128785 Simplifying x + 0.25 = -0.229128785 Reorder the terms: 0.25 + x = -0.229128785 Solving 0.25 + x = -0.229128785 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.25' to each side of the equation. 0.25 + -0.25 + x = -0.229128785 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + x = -0.229128785 + -0.25 x = -0.229128785 + -0.25 Combine like terms: -0.229128785 + -0.25 = -0.479128785 x = -0.479128785 Simplifying x = -0.479128785Solution
