Simplifying 20x2 + -18x + 3 = 0 Reorder the terms: 3 + -18x + 20x2 = 0 Solving 3 + -18x + 20x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. 0.15 + -0.9x + x2 = 0 Move the constant term to the right: Add '-0.15' to each side of the equation. 0.15 + -0.9x + -0.15 + x2 = 0 + -0.15 Reorder the terms: 0.15 + -0.15 + -0.9x + x2 = 0 + -0.15 Combine like terms: 0.15 + -0.15 = 0.00 0.00 + -0.9x + x2 = 0 + -0.15 -0.9x + x2 = 0 + -0.15 Combine like terms: 0 + -0.15 = -0.15 -0.9x + x2 = -0.15 The x term is -0.9x. Take half its coefficient (-0.45). Square it (0.2025) and add it to both sides. Add '0.2025' to each side of the equation. -0.9x + 0.2025 + x2 = -0.15 + 0.2025 Reorder the terms: 0.2025 + -0.9x + x2 = -0.15 + 0.2025 Combine like terms: -0.15 + 0.2025 = 0.0525 0.2025 + -0.9x + x2 = 0.0525 Factor a perfect square on the left side: (x + -0.45)(x + -0.45) = 0.0525 Calculate the square root of the right side: 0.229128785 Break this problem into two subproblems by setting (x + -0.45) equal to 0.229128785 and -0.229128785.Subproblem 1
x + -0.45 = 0.229128785 Simplifying x + -0.45 = 0.229128785 Reorder the terms: -0.45 + x = 0.229128785 Solving -0.45 + x = 0.229128785 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.45' to each side of the equation. -0.45 + 0.45 + x = 0.229128785 + 0.45 Combine like terms: -0.45 + 0.45 = 0.00 0.00 + x = 0.229128785 + 0.45 x = 0.229128785 + 0.45 Combine like terms: 0.229128785 + 0.45 = 0.679128785 x = 0.679128785 Simplifying x = 0.679128785Subproblem 2
x + -0.45 = -0.229128785 Simplifying x + -0.45 = -0.229128785 Reorder the terms: -0.45 + x = -0.229128785 Solving -0.45 + x = -0.229128785 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.45' to each side of the equation. -0.45 + 0.45 + x = -0.229128785 + 0.45 Combine like terms: -0.45 + 0.45 = 0.00 0.00 + x = -0.229128785 + 0.45 x = -0.229128785 + 0.45 Combine like terms: -0.229128785 + 0.45 = 0.220871215 x = 0.220871215 Simplifying x = 0.220871215Solution
