Simplifying 4x2 + 11x + -25 = 0 Reorder the terms: -25 + 11x + 4x2 = 0 Solving -25 + 11x + 4x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 4 the coefficient of the squared term: Divide each side by '4'. -6.25 + 2.75x + x2 = 0 Move the constant term to the right: Add '6.25' to each side of the equation. -6.25 + 2.75x + 6.25 + x2 = 0 + 6.25 Reorder the terms: -6.25 + 6.25 + 2.75x + x2 = 0 + 6.25 Combine like terms: -6.25 + 6.25 = 0.00 0.00 + 2.75x + x2 = 0 + 6.25 2.75x + x2 = 0 + 6.25 Combine like terms: 0 + 6.25 = 6.25 2.75x + x2 = 6.25 The x term is 2.75x. Take half its coefficient (1.375). Square it (1.890625) and add it to both sides. Add '1.890625' to each side of the equation. 2.75x + 1.890625 + x2 = 6.25 + 1.890625 Reorder the terms: 1.890625 + 2.75x + x2 = 6.25 + 1.890625 Combine like terms: 6.25 + 1.890625 = 8.140625 1.890625 + 2.75x + x2 = 8.140625 Factor a perfect square on the left side: (x + 1.375)(x + 1.375) = 8.140625 Calculate the square root of the right side: 2.853178053 Break this problem into two subproblems by setting (x + 1.375) equal to 2.853178053 and -2.853178053.Subproblem 1
x + 1.375 = 2.853178053 Simplifying x + 1.375 = 2.853178053 Reorder the terms: 1.375 + x = 2.853178053 Solving 1.375 + x = 2.853178053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.375' to each side of the equation. 1.375 + -1.375 + x = 2.853178053 + -1.375 Combine like terms: 1.375 + -1.375 = 0.000 0.000 + x = 2.853178053 + -1.375 x = 2.853178053 + -1.375 Combine like terms: 2.853178053 + -1.375 = 1.478178053 x = 1.478178053 Simplifying x = 1.478178053Subproblem 2
x + 1.375 = -2.853178053 Simplifying x + 1.375 = -2.853178053 Reorder the terms: 1.375 + x = -2.853178053 Solving 1.375 + x = -2.853178053 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.375' to each side of the equation. 1.375 + -1.375 + x = -2.853178053 + -1.375 Combine like terms: 1.375 + -1.375 = 0.000 0.000 + x = -2.853178053 + -1.375 x = -2.853178053 + -1.375 Combine like terms: -2.853178053 + -1.375 = -4.228178053 x = -4.228178053 Simplifying x = -4.228178053Solution
