Simplifying 2x2 + 12x + 7 = 0 Reorder the terms: 7 + 12x + 2x2 = 0 Solving 7 + 12x + 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'. 3.5 + 6x + x2 = 0 Move the constant term to the right: Add '-3.5' to each side of the equation. 3.5 + 6x + -3.5 + x2 = 0 + -3.5 Reorder the terms: 3.5 + -3.5 + 6x + x2 = 0 + -3.5 Combine like terms: 3.5 + -3.5 = 0.0 0.0 + 6x + x2 = 0 + -3.5 6x + x2 = 0 + -3.5 Combine like terms: 0 + -3.5 = -3.5 6x + x2 = -3.5 The x term is 6x. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6x + 9 + x2 = -3.5 + 9 Reorder the terms: 9 + 6x + x2 = -3.5 + 9 Combine like terms: -3.5 + 9 = 5.5 9 + 6x + x2 = 5.5 Factor a perfect square on the left side: (x + 3)(x + 3) = 5.5 Calculate the square root of the right side: 2.34520788 Break this problem into two subproblems by setting (x + 3) equal to 2.34520788 and -2.34520788.Subproblem 1
x + 3 = 2.34520788 Simplifying x + 3 = 2.34520788 Reorder the terms: 3 + x = 2.34520788 Solving 3 + x = 2.34520788 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = 2.34520788 + -3 Combine like terms: 3 + -3 = 0 0 + x = 2.34520788 + -3 x = 2.34520788 + -3 Combine like terms: 2.34520788 + -3 = -0.65479212 x = -0.65479212 Simplifying x = -0.65479212Subproblem 2
x + 3 = -2.34520788 Simplifying x + 3 = -2.34520788 Reorder the terms: 3 + x = -2.34520788 Solving 3 + x = -2.34520788 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + x = -2.34520788 + -3 Combine like terms: 3 + -3 = 0 0 + x = -2.34520788 + -3 x = -2.34520788 + -3 Combine like terms: -2.34520788 + -3 = -5.34520788 x = -5.34520788 Simplifying x = -5.34520788Solution
