Simplifying 2x2 + 7x + 2 = 0 Reorder the terms: 2 + 7x + 2x2 = 0 Solving 2 + 7x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 1 + 3.5x + x2 = 0 Move the constant term to the right: Add '-1' to each side of the equation. 1 + 3.5x + -1 + x2 = 0 + -1 Reorder the terms: 1 + -1 + 3.5x + x2 = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 3.5x + x2 = 0 + -1 3.5x + x2 = 0 + -1 Combine like terms: 0 + -1 = -1 3.5x + x2 = -1 The x term is 3.5x. Take half its coefficient (1.75). Square it (3.0625) and add it to both sides. Add '3.0625' to each side of the equation. 3.5x + 3.0625 + x2 = -1 + 3.0625 Reorder the terms: 3.0625 + 3.5x + x2 = -1 + 3.0625 Combine like terms: -1 + 3.0625 = 2.0625 3.0625 + 3.5x + x2 = 2.0625 Factor a perfect square on the left side: (x + 1.75)(x + 1.75) = 2.0625 Calculate the square root of the right side: 1.436140662 Break this problem into two subproblems by setting (x + 1.75) equal to 1.436140662 and -1.436140662.Subproblem 1
x + 1.75 = 1.436140662 Simplifying x + 1.75 = 1.436140662 Reorder the terms: 1.75 + x = 1.436140662 Solving 1.75 + x = 1.436140662 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = 1.436140662 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = 1.436140662 + -1.75 x = 1.436140662 + -1.75 Combine like terms: 1.436140662 + -1.75 = -0.313859338 x = -0.313859338 Simplifying x = -0.313859338Subproblem 2
x + 1.75 = -1.436140662 Simplifying x + 1.75 = -1.436140662 Reorder the terms: 1.75 + x = -1.436140662 Solving 1.75 + x = -1.436140662 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.75' to each side of the equation. 1.75 + -1.75 + x = -1.436140662 + -1.75 Combine like terms: 1.75 + -1.75 = 0.00 0.00 + x = -1.436140662 + -1.75 x = -1.436140662 + -1.75 Combine like terms: -1.436140662 + -1.75 = -3.186140662 x = -3.186140662 Simplifying x = -3.186140662Solution
The solution to the problem is based on the solutions from the subproblems. x = {-0.313859338, -3.186140662}
