Simplifying (X + 2)(X + -9) = 24 Reorder the terms: (2 + X)(X + -9) = 24 Reorder the terms: (2 + X)(-9 + X) = 24 Multiply (2 + X) * (-9 + X) (2(-9 + X) + X(-9 + X)) = 24 ((-9 * 2 + X * 2) + X(-9 + X)) = 24 ((-18 + 2X) + X(-9 + X)) = 24 (-18 + 2X + (-9 * X + X * X)) = 24 (-18 + 2X + (-9X + X2)) = 24 Combine like terms: 2X + -9X = -7X (-18 + -7X + X2) = 24 Solving -18 + -7X + X2 = 24 Solving for variable 'X'. Reorder the terms: -18 + -24 + -7X + X2 = 24 + -24 Combine like terms: -18 + -24 = -42 -42 + -7X + X2 = 24 + -24 Combine like terms: 24 + -24 = 0 -42 + -7X + X2 = 0 Begin completing the square. Move the constant term to the right: Add '42' to each side of the equation. -42 + -7X + 42 + X2 = 0 + 42 Reorder the terms: -42 + 42 + -7X + X2 = 0 + 42 Combine like terms: -42 + 42 = 0 0 + -7X + X2 = 0 + 42 -7X + X2 = 0 + 42 Combine like terms: 0 + 42 = 42 -7X + X2 = 42 The X term is -7X. Take half its coefficient (-3.5). Square it (12.25) and add it to both sides. Add '12.25' to each side of the equation. -7X + 12.25 + X2 = 42 + 12.25 Reorder the terms: 12.25 + -7X + X2 = 42 + 12.25 Combine like terms: 42 + 12.25 = 54.25 12.25 + -7X + X2 = 54.25 Factor a perfect square on the left side: (X + -3.5)(X + -3.5) = 54.25 Calculate the square root of the right side: 7.365459931 Break this problem into two subproblems by setting (X + -3.5) equal to 7.365459931 and -7.365459931.Subproblem 1
X + -3.5 = 7.365459931 Simplifying X + -3.5 = 7.365459931 Reorder the terms: -3.5 + X = 7.365459931 Solving -3.5 + X = 7.365459931 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + X = 7.365459931 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + X = 7.365459931 + 3.5 X = 7.365459931 + 3.5 Combine like terms: 7.365459931 + 3.5 = 10.865459931 X = 10.865459931 Simplifying X = 10.865459931Subproblem 2
X + -3.5 = -7.365459931 Simplifying X + -3.5 = -7.365459931 Reorder the terms: -3.5 + X = -7.365459931 Solving -3.5 + X = -7.365459931 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '3.5' to each side of the equation. -3.5 + 3.5 + X = -7.365459931 + 3.5 Combine like terms: -3.5 + 3.5 = 0.0 0.0 + X = -7.365459931 + 3.5 X = -7.365459931 + 3.5 Combine like terms: -7.365459931 + 3.5 = -3.865459931 X = -3.865459931 Simplifying X = -3.865459931Solution
The solution to the problem is based on the solutions from the subproblems. X = {10.865459931, -3.865459931}
