Simplifying 25x2 + 63x + -20 = 0 Reorder the terms: -20 + 63x + 25x2 = 0 Solving -20 + 63x + 25x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 25 the coefficient of the squared term: Divide each side by '25'. -0.8 + 2.52x + x2 = 0 Move the constant term to the right: Add '0.8' to each side of the equation. -0.8 + 2.52x + 0.8 + x2 = 0 + 0.8 Reorder the terms: -0.8 + 0.8 + 2.52x + x2 = 0 + 0.8 Combine like terms: -0.8 + 0.8 = 0.0 0.0 + 2.52x + x2 = 0 + 0.8 2.52x + x2 = 0 + 0.8 Combine like terms: 0 + 0.8 = 0.8 2.52x + x2 = 0.8 The x term is 2.52x. Take half its coefficient (1.26). Square it (1.5876) and add it to both sides. Add '1.5876' to each side of the equation. 2.52x + 1.5876 + x2 = 0.8 + 1.5876 Reorder the terms: 1.5876 + 2.52x + x2 = 0.8 + 1.5876 Combine like terms: 0.8 + 1.5876 = 2.3876 1.5876 + 2.52x + x2 = 2.3876 Factor a perfect square on the left side: (x + 1.26)(x + 1.26) = 2.3876 Calculate the square root of the right side: 1.545186073 Break this problem into two subproblems by setting (x + 1.26) equal to 1.545186073 and -1.545186073.Subproblem 1
x + 1.26 = 1.545186073 Simplifying x + 1.26 = 1.545186073 Reorder the terms: 1.26 + x = 1.545186073 Solving 1.26 + x = 1.545186073 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.26' to each side of the equation. 1.26 + -1.26 + x = 1.545186073 + -1.26 Combine like terms: 1.26 + -1.26 = 0.00 0.00 + x = 1.545186073 + -1.26 x = 1.545186073 + -1.26 Combine like terms: 1.545186073 + -1.26 = 0.285186073 x = 0.285186073 Simplifying x = 0.285186073Subproblem 2
x + 1.26 = -1.545186073 Simplifying x + 1.26 = -1.545186073 Reorder the terms: 1.26 + x = -1.545186073 Solving 1.26 + x = -1.545186073 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.26' to each side of the equation. 1.26 + -1.26 + x = -1.545186073 + -1.26 Combine like terms: 1.26 + -1.26 = 0.00 0.00 + x = -1.545186073 + -1.26 x = -1.545186073 + -1.26 Combine like terms: -1.545186073 + -1.26 = -2.805186073 x = -2.805186073 Simplifying x = -2.805186073Solution
