Simplifying (x2 + 9x + 3) + (7x + -8) = 0 Reorder the terms: (3 + 9x + x2) + (7x + -8) = 0 Remove parenthesis around (3 + 9x + x2) 3 + 9x + x2 + (7x + -8) = 0 Reorder the terms: 3 + 9x + x2 + (-8 + 7x) = 0 Remove parenthesis around (-8 + 7x) 3 + 9x + x2 + -8 + 7x = 0 Reorder the terms: 3 + -8 + 9x + 7x + x2 = 0 Combine like terms: 3 + -8 = -5 -5 + 9x + 7x + x2 = 0 Combine like terms: 9x + 7x = 16x -5 + 16x + x2 = 0 Solving -5 + 16x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '5' to each side of the equation. -5 + 16x + 5 + x2 = 0 + 5 Reorder the terms: -5 + 5 + 16x + x2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 16x + x2 = 0 + 5 16x + x2 = 0 + 5 Combine like terms: 0 + 5 = 5 16x + x2 = 5 The x term is 16x. Take half its coefficient (8). Square it (64) and add it to both sides. Add '64' to each side of the equation. 16x + 64 + x2 = 5 + 64 Reorder the terms: 64 + 16x + x2 = 5 + 64 Combine like terms: 5 + 64 = 69 64 + 16x + x2 = 69 Factor a perfect square on the left side: (x + 8)(x + 8) = 69 Calculate the square root of the right side: 8.306623863 Break this problem into two subproblems by setting (x + 8) equal to 8.306623863 and -8.306623863.Subproblem 1
x + 8 = 8.306623863 Simplifying x + 8 = 8.306623863 Reorder the terms: 8 + x = 8.306623863 Solving 8 + x = 8.306623863 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + x = 8.306623863 + -8 Combine like terms: 8 + -8 = 0 0 + x = 8.306623863 + -8 x = 8.306623863 + -8 Combine like terms: 8.306623863 + -8 = 0.306623863 x = 0.306623863 Simplifying x = 0.306623863Subproblem 2
x + 8 = -8.306623863 Simplifying x + 8 = -8.306623863 Reorder the terms: 8 + x = -8.306623863 Solving 8 + x = -8.306623863 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + x = -8.306623863 + -8 Combine like terms: 8 + -8 = 0 0 + x = -8.306623863 + -8 x = -8.306623863 + -8 Combine like terms: -8.306623863 + -8 = -16.306623863 x = -16.306623863 Simplifying x = -16.306623863Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.306623863, -16.306623863}
