Simplifying 0 = -5x2 + -20x + 3 Reorder the terms: 0 = 3 + -20x + -5x2 Solving 0 = 3 + -20x + -5x2 Solving for variable 'x'. Combine like terms: 0 + -3 = -3 -3 + 20x + 5x2 = 3 + -20x + -5x2 + -3 + 20x + 5x2 Reorder the terms: -3 + 20x + 5x2 = 3 + -3 + -20x + 20x + -5x2 + 5x2 Combine like terms: 3 + -3 = 0 -3 + 20x + 5x2 = 0 + -20x + 20x + -5x2 + 5x2 -3 + 20x + 5x2 = -20x + 20x + -5x2 + 5x2 Combine like terms: -20x + 20x = 0 -3 + 20x + 5x2 = 0 + -5x2 + 5x2 -3 + 20x + 5x2 = -5x2 + 5x2 Combine like terms: -5x2 + 5x2 = 0 -3 + 20x + 5x2 = 0 Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. -0.6 + 4x + x2 = 0 Move the constant term to the right: Add '0.6' to each side of the equation. -0.6 + 4x + 0.6 + x2 = 0 + 0.6 Reorder the terms: -0.6 + 0.6 + 4x + x2 = 0 + 0.6 Combine like terms: -0.6 + 0.6 = 0.0 0.0 + 4x + x2 = 0 + 0.6 4x + x2 = 0 + 0.6 Combine like terms: 0 + 0.6 = 0.6 4x + x2 = 0.6 The x term is 4x. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4x + 4 + x2 = 0.6 + 4 Reorder the terms: 4 + 4x + x2 = 0.6 + 4 Combine like terms: 0.6 + 4 = 4.6 4 + 4x + x2 = 4.6 Factor a perfect square on the left side: (x + 2)(x + 2) = 4.6 Calculate the square root of the right side: 2.144761059 Break this problem into two subproblems by setting (x + 2) equal to 2.144761059 and -2.144761059.Subproblem 1
x + 2 = 2.144761059 Simplifying x + 2 = 2.144761059 Reorder the terms: 2 + x = 2.144761059 Solving 2 + x = 2.144761059 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = 2.144761059 + -2 Combine like terms: 2 + -2 = 0 0 + x = 2.144761059 + -2 x = 2.144761059 + -2 Combine like terms: 2.144761059 + -2 = 0.144761059 x = 0.144761059 Simplifying x = 0.144761059Subproblem 2
x + 2 = -2.144761059 Simplifying x + 2 = -2.144761059 Reorder the terms: 2 + x = -2.144761059 Solving 2 + x = -2.144761059 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + x = -2.144761059 + -2 Combine like terms: 2 + -2 = 0 0 + x = -2.144761059 + -2 x = -2.144761059 + -2 Combine like terms: -2.144761059 + -2 = -4.144761059 x = -4.144761059 Simplifying x = -4.144761059Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.144761059, -4.144761059}
