Simplifying 2x2 + 6x + -71 = 0 Reorder the terms: -71 + 6x + 2x2 = 0 Solving -71 + 6x + 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'. -35.5 + 3x + x2 = 0 Move the constant term to the right: Add '35.5' to each side of the equation. -35.5 + 3x + 35.5 + x2 = 0 + 35.5 Reorder the terms: -35.5 + 35.5 + 3x + x2 = 0 + 35.5 Combine like terms: -35.5 + 35.5 = 0.0 0.0 + 3x + x2 = 0 + 35.5 3x + x2 = 0 + 35.5 Combine like terms: 0 + 35.5 = 35.5 3x + x2 = 35.5 The x term is 3x. Take half its coefficient (1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. 3x + 2.25 + x2 = 35.5 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 35.5 + 2.25 Combine like terms: 35.5 + 2.25 = 37.75 2.25 + 3x + x2 = 37.75 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 37.75 Calculate the square root of the right side: 6.144102864 Break this problem into two subproblems by setting (x + 1.5) equal to 6.144102864 and -6.144102864.Subproblem 1
x + 1.5 = 6.144102864 Simplifying x + 1.5 = 6.144102864 Reorder the terms: 1.5 + x = 6.144102864 Solving 1.5 + x = 6.144102864 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = 6.144102864 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 6.144102864 + -1.5 x = 6.144102864 + -1.5 Combine like terms: 6.144102864 + -1.5 = 4.644102864 x = 4.644102864 Simplifying x = 4.644102864Subproblem 2
x + 1.5 = -6.144102864 Simplifying x + 1.5 = -6.144102864 Reorder the terms: 1.5 + x = -6.144102864 Solving 1.5 + x = -6.144102864 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.5' to each side of the equation. 1.5 + -1.5 + x = -6.144102864 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -6.144102864 + -1.5 x = -6.144102864 + -1.5 Combine like terms: -6.144102864 + -1.5 = -7.644102864 x = -7.644102864 Simplifying x = -7.644102864Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.644102864, -7.644102864}
