Simplifying 8x2 + -100x + -15 = 0 Reorder the terms: -15 + -100x + 8x2 = 0 Solving -15 + -100x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -1.875 + -12.5x + x2 = 0 Move the constant term to the right: Add '1.875' to each side of the equation. -1.875 + -12.5x + 1.875 + x2 = 0 + 1.875 Reorder the terms: -1.875 + 1.875 + -12.5x + x2 = 0 + 1.875 Combine like terms: -1.875 + 1.875 = 0.000 0.000 + -12.5x + x2 = 0 + 1.875 -12.5x + x2 = 0 + 1.875 Combine like terms: 0 + 1.875 = 1.875 -12.5x + x2 = 1.875 The x term is -12.5x. Take half its coefficient (-6.25). Square it (39.0625) and add it to both sides. Add '39.0625' to each side of the equation. -12.5x + 39.0625 + x2 = 1.875 + 39.0625 Reorder the terms: 39.0625 + -12.5x + x2 = 1.875 + 39.0625 Combine like terms: 1.875 + 39.0625 = 40.9375 39.0625 + -12.5x + x2 = 40.9375 Factor a perfect square on the left side: (x + -6.25)(x + -6.25) = 40.9375 Calculate the square root of the right side: 6.398241946 Break this problem into two subproblems by setting (x + -6.25) equal to 6.398241946 and -6.398241946.Subproblem 1
x + -6.25 = 6.398241946 Simplifying x + -6.25 = 6.398241946 Reorder the terms: -6.25 + x = 6.398241946 Solving -6.25 + x = 6.398241946 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6.25' to each side of the equation. -6.25 + 6.25 + x = 6.398241946 + 6.25 Combine like terms: -6.25 + 6.25 = 0.00 0.00 + x = 6.398241946 + 6.25 x = 6.398241946 + 6.25 Combine like terms: 6.398241946 + 6.25 = 12.648241946 x = 12.648241946 Simplifying x = 12.648241946Subproblem 2
x + -6.25 = -6.398241946 Simplifying x + -6.25 = -6.398241946 Reorder the terms: -6.25 + x = -6.398241946 Solving -6.25 + x = -6.398241946 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '6.25' to each side of the equation. -6.25 + 6.25 + x = -6.398241946 + 6.25 Combine like terms: -6.25 + 6.25 = 0.00 0.00 + x = -6.398241946 + 6.25 x = -6.398241946 + 6.25 Combine like terms: -6.398241946 + 6.25 = -0.148241946 x = -0.148241946 Simplifying x = -0.148241946Solution
