Simplifying 8x2 + -15x + -8 = 0 Reorder the terms: -8 + -15x + 8x2 = 0 Solving -8 + -15x + 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 + -1.875x + x2 = 0 Move the constant term to the right: Add '1' to each side of the equation. -1 + -1.875x + 1 + x2 = 0 + 1 Reorder the terms: -1 + 1 + -1.875x + x2 = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -1.875x + x2 = 0 + 1 -1.875x + x2 = 0 + 1 Combine like terms: 0 + 1 = 1 -1.875x + x2 = 1 The x term is -1.875x. Take half its coefficient (-0.9375). Square it (0.87890625) and add it to both sides. Add '0.87890625' to each side of the equation. -1.875x + 0.87890625 + x2 = 1 + 0.87890625 Reorder the terms: 0.87890625 + -1.875x + x2 = 1 + 0.87890625 Combine like terms: 1 + 0.87890625 = 1.87890625 0.87890625 + -1.875x + x2 = 1.87890625 Factor a perfect square on the left side: (x + -0.9375)(x + -0.9375) = 1.87890625 Calculate the square root of the right side: 1.370732012 Break this problem into two subproblems by setting (x + -0.9375) equal to 1.370732012 and -1.370732012.Subproblem 1
x + -0.9375 = 1.370732012 Simplifying x + -0.9375 = 1.370732012 Reorder the terms: -0.9375 + x = 1.370732012 Solving -0.9375 + x = 1.370732012 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.9375' to each side of the equation. -0.9375 + 0.9375 + x = 1.370732012 + 0.9375 Combine like terms: -0.9375 + 0.9375 = 0.0000 0.0000 + x = 1.370732012 + 0.9375 x = 1.370732012 + 0.9375 Combine like terms: 1.370732012 + 0.9375 = 2.308232012 x = 2.308232012 Simplifying x = 2.308232012Subproblem 2
x + -0.9375 = -1.370732012 Simplifying x + -0.9375 = -1.370732012 Reorder the terms: -0.9375 + x = -1.370732012 Solving -0.9375 + x = -1.370732012 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.9375' to each side of the equation. -0.9375 + 0.9375 + x = -1.370732012 + 0.9375 Combine like terms: -0.9375 + 0.9375 = 0.0000 0.0000 + x = -1.370732012 + 0.9375 x = -1.370732012 + 0.9375 Combine like terms: -1.370732012 + 0.9375 = -0.433232012 x = -0.433232012 Simplifying x = -0.433232012Solution
