Simplifying (x + -8)(x + 9) = 7 Reorder the terms: (-8 + x)(x + 9) = 7 Reorder the terms: (-8 + x)(9 + x) = 7 Multiply (-8 + x) * (9 + x) (-8(9 + x) + x(9 + x)) = 7 ((9 * -8 + x * -8) + x(9 + x)) = 7 ((-72 + -8x) + x(9 + x)) = 7 (-72 + -8x + (9 * x + x * x)) = 7 (-72 + -8x + (9x + x2)) = 7 Combine like terms: -8x + 9x = 1x (-72 + 1x + x2) = 7 Solving -72 + 1x + x2 = 7 Solving for variable 'x'. Reorder the terms: -72 + -7 + 1x + x2 = 7 + -7 Combine like terms: -72 + -7 = -79 -79 + 1x + x2 = 7 + -7 Combine like terms: 7 + -7 = 0 -79 + 1x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '79' to each side of the equation. -79 + 1x + 79 + x2 = 0 + 79 Reorder the terms: -79 + 79 + 1x + x2 = 0 + 79 Combine like terms: -79 + 79 = 0 0 + 1x + x2 = 0 + 79 1x + x2 = 0 + 79 Combine like terms: 0 + 79 = 79 1x + x2 = 79 The x term is 1x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. x + 0.25 + x2 = 79 + 0.25 Reorder the terms: 0.25 + x + x2 = 79 + 0.25 Combine like terms: 79 + 0.25 = 79.25 0.25 + x + x2 = 79.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 79.25 Calculate the square root of the right side: 8.902246907 Break this problem into two subproblems by setting (x + 0.5) equal to 8.902246907 and -8.902246907.Subproblem 1
x + 0.5 = 8.902246907 Simplifying x + 0.5 = 8.902246907 Reorder the terms: 0.5 + x = 8.902246907 Solving 0.5 + x = 8.902246907 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 8.902246907 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 8.902246907 + -0.5 x = 8.902246907 + -0.5 Combine like terms: 8.902246907 + -0.5 = 8.402246907 x = 8.402246907 Simplifying x = 8.402246907Subproblem 2
x + 0.5 = -8.902246907 Simplifying x + 0.5 = -8.902246907 Reorder the terms: 0.5 + x = -8.902246907 Solving 0.5 + x = -8.902246907 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -8.902246907 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -8.902246907 + -0.5 x = -8.902246907 + -0.5 Combine like terms: -8.902246907 + -0.5 = -9.402246907 x = -9.402246907 Simplifying x = -9.402246907Solution
The solution to the problem is based on the solutions from the subproblems. x = {8.402246907, -9.402246907}
