Simplifying 4.20 = 4x2 + -8x + 4 Reorder the terms: 4.20 = 4 + -8x + 4x2 Solving 4.20 = 4 + -8x + 4x2 Solving for variable 'x'. Combine like terms: 4.20 + -4 = 0.2 0.2 + 8x + -4x2 = 4 + -8x + 4x2 + -4 + 8x + -4x2 Reorder the terms: 0.2 + 8x + -4x2 = 4 + -4 + -8x + 8x + 4x2 + -4x2 Combine like terms: 4 + -4 = 0 0.2 + 8x + -4x2 = 0 + -8x + 8x + 4x2 + -4x2 0.2 + 8x + -4x2 = -8x + 8x + 4x2 + -4x2 Combine like terms: -8x + 8x = 0 0.2 + 8x + -4x2 = 0 + 4x2 + -4x2 0.2 + 8x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 0.2 + 8x + -4x2 = 0 Begin completing the square. Divide all terms by -4 the coefficient of the squared term: Divide each side by '-4'. -0.05 + -2x + x2 = 0 Move the constant term to the right: Add '0.05' to each side of the equation. -0.05 + -2x + 0.05 + x2 = 0 + 0.05 Reorder the terms: -0.05 + 0.05 + -2x + x2 = 0 + 0.05 Combine like terms: -0.05 + 0.05 = 0.00 0.00 + -2x + x2 = 0 + 0.05 -2x + x2 = 0 + 0.05 Combine like terms: 0 + 0.05 = 0.05 -2x + x2 = 0.05 The x term is -2x. Take half its coefficient (-1). Square it (1) and add it to both sides. Add '1' to each side of the equation. -2x + 1 + x2 = 0.05 + 1 Reorder the terms: 1 + -2x + x2 = 0.05 + 1 Combine like terms: 0.05 + 1 = 1.05 1 + -2x + x2 = 1.05 Factor a perfect square on the left side: (x + -1)(x + -1) = 1.05 Calculate the square root of the right side: 1.024695077 Break this problem into two subproblems by setting (x + -1) equal to 1.024695077 and -1.024695077.Subproblem 1
x + -1 = 1.024695077 Simplifying x + -1 = 1.024695077 Reorder the terms: -1 + x = 1.024695077 Solving -1 + x = 1.024695077 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = 1.024695077 + 1 Combine like terms: -1 + 1 = 0 0 + x = 1.024695077 + 1 x = 1.024695077 + 1 Combine like terms: 1.024695077 + 1 = 2.024695077 x = 2.024695077 Simplifying x = 2.024695077Subproblem 2
x + -1 = -1.024695077 Simplifying x + -1 = -1.024695077 Reorder the terms: -1 + x = -1.024695077 Solving -1 + x = -1.024695077 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x = -1.024695077 + 1 Combine like terms: -1 + 1 = 0 0 + x = -1.024695077 + 1 x = -1.024695077 + 1 Combine like terms: -1.024695077 + 1 = -0.024695077 x = -0.024695077 Simplifying x = -0.024695077Solution
The solution to the problem is based on the solutions from the subproblems. x = {2.024695077, -0.024695077}
