Simplifying 5x2 + 40x + 8 = 0 Reorder the terms: 8 + 40x + 5x2 = 0 Solving 8 + 40x + 5x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 5 the coefficient of the squared term: Divide each side by '5'. 1.6 + 8x + x2 = 0 Move the constant term to the right: Add '-1.6' to each side of the equation. 1.6 + 8x + -1.6 + x2 = 0 + -1.6 Reorder the terms: 1.6 + -1.6 + 8x + x2 = 0 + -1.6 Combine like terms: 1.6 + -1.6 = 0.0 0.0 + 8x + x2 = 0 + -1.6 8x + x2 = 0 + -1.6 Combine like terms: 0 + -1.6 = -1.6 8x + x2 = -1.6 The x term is 8x. Take half its coefficient (4). Square it (16) and add it to both sides. Add '16' to each side of the equation. 8x + 16 + x2 = -1.6 + 16 Reorder the terms: 16 + 8x + x2 = -1.6 + 16 Combine like terms: -1.6 + 16 = 14.4 16 + 8x + x2 = 14.4 Factor a perfect square on the left side: (x + 4)(x + 4) = 14.4 Calculate the square root of the right side: 3.794733192 Break this problem into two subproblems by setting (x + 4) equal to 3.794733192 and -3.794733192.Subproblem 1
x + 4 = 3.794733192 Simplifying x + 4 = 3.794733192 Reorder the terms: 4 + x = 3.794733192 Solving 4 + x = 3.794733192 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = 3.794733192 + -4 Combine like terms: 4 + -4 = 0 0 + x = 3.794733192 + -4 x = 3.794733192 + -4 Combine like terms: 3.794733192 + -4 = -0.205266808 x = -0.205266808 Simplifying x = -0.205266808Subproblem 2
x + 4 = -3.794733192 Simplifying x + 4 = -3.794733192 Reorder the terms: 4 + x = -3.794733192 Solving 4 + x = -3.794733192 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + x = -3.794733192 + -4 Combine like terms: 4 + -4 = 0 0 + x = -3.794733192 + -4 x = -3.794733192 + -4 Combine like terms: -3.794733192 + -4 = -7.794733192 x = -7.794733192 Simplifying x = -7.794733192Solution
