Simplifying 20x2 + 5 = 21x Reorder the terms: 5 + 20x2 = 21x Solving 5 + 20x2 = 21x Solving for variable 'x'. Reorder the terms: 5 + -21x + 20x2 = 21x + -21x Combine like terms: 21x + -21x = 0 5 + -21x + 20x2 = 0 Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. 0.25 + -1.05x + x2 = 0 Move the constant term to the right: Add '-0.25' to each side of the equation. 0.25 + -1.05x + -0.25 + x2 = 0 + -0.25 Reorder the terms: 0.25 + -0.25 + -1.05x + x2 = 0 + -0.25 Combine like terms: 0.25 + -0.25 = 0.00 0.00 + -1.05x + x2 = 0 + -0.25 -1.05x + x2 = 0 + -0.25 Combine like terms: 0 + -0.25 = -0.25 -1.05x + x2 = -0.25 The x term is -1.05x. Take half its coefficient (-0.525). Square it (0.275625) and add it to both sides. Add '0.275625' to each side of the equation. -1.05x + 0.275625 + x2 = -0.25 + 0.275625 Reorder the terms: 0.275625 + -1.05x + x2 = -0.25 + 0.275625 Combine like terms: -0.25 + 0.275625 = 0.025625 0.275625 + -1.05x + x2 = 0.025625 Factor a perfect square on the left side: (x + -0.525)(x + -0.525) = 0.025625 Calculate the square root of the right side: 0.160078106 Break this problem into two subproblems by setting (x + -0.525) equal to 0.160078106 and -0.160078106.Subproblem 1
x + -0.525 = 0.160078106 Simplifying x + -0.525 = 0.160078106 Reorder the terms: -0.525 + x = 0.160078106 Solving -0.525 + x = 0.160078106 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.525' to each side of the equation. -0.525 + 0.525 + x = 0.160078106 + 0.525 Combine like terms: -0.525 + 0.525 = 0.000 0.000 + x = 0.160078106 + 0.525 x = 0.160078106 + 0.525 Combine like terms: 0.160078106 + 0.525 = 0.685078106 x = 0.685078106 Simplifying x = 0.685078106Subproblem 2
x + -0.525 = -0.160078106 Simplifying x + -0.525 = -0.160078106 Reorder the terms: -0.525 + x = -0.160078106 Solving -0.525 + x = -0.160078106 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.525' to each side of the equation. -0.525 + 0.525 + x = -0.160078106 + 0.525 Combine like terms: -0.525 + 0.525 = 0.000 0.000 + x = -0.160078106 + 0.525 x = -0.160078106 + 0.525 Combine like terms: -0.160078106 + 0.525 = 0.364921894 x = 0.364921894 Simplifying x = 0.364921894Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.685078106, 0.364921894}
