Simplifying (x + -7)(x + 4) = 2 Reorder the terms: (-7 + x)(x + 4) = 2 Reorder the terms: (-7 + x)(4 + x) = 2 Multiply (-7 + x) * (4 + x) (-7(4 + x) + x(4 + x)) = 2 ((4 * -7 + x * -7) + x(4 + x)) = 2 ((-28 + -7x) + x(4 + x)) = 2 (-28 + -7x + (4 * x + x * x)) = 2 (-28 + -7x + (4x + x2)) = 2 Combine like terms: -7x + 4x = -3x (-28 + -3x + x2) = 2 Solving -28 + -3x + x2 = 2 Solving for variable 'x'. Reorder the terms: -28 + -2 + -3x + x2 = 2 + -2 Combine like terms: -28 + -2 = -30 -30 + -3x + x2 = 2 + -2 Combine like terms: 2 + -2 = 0 -30 + -3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '30' to each side of the equation. -30 + -3x + 30 + x2 = 0 + 30 Reorder the terms: -30 + 30 + -3x + x2 = 0 + 30 Combine like terms: -30 + 30 = 0 0 + -3x + x2 = 0 + 30 -3x + x2 = 0 + 30 Combine like terms: 0 + 30 = 30 -3x + x2 = 30 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 = 30 + 2.25 Reorder the terms: 2.25 + -3x + x2 = 30 + 2.25 Combine like terms: 30 + 2.25 = 32.25 2.25 + -3x + x2 = 32.25 Factor a perfect square on the left side: (x + -1.5)(x + -1.5) = 32.25 Calculate the square root of the right side: 5.678908346 Break this problem into two subproblems by setting (x + -1.5) equal to 5.678908346 and -5.678908346.Subproblem 1
x + -1.5 = 5.678908346 Simplifying x + -1.5 = 5.678908346 Reorder the terms: -1.5 + x = 5.678908346 Solving -1.5 + x = 5.678908346 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 = 5.678908346 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = 5.678908346 + 1.5 x = 5.678908346 + 1.5 Combine like terms: 5.678908346 + 1.5 = 7.178908346 x = 7.178908346 Simplifying x = 7.178908346Subproblem 2
x + -1.5 = -5.678908346 Simplifying x + -1.5 = -5.678908346 Reorder the terms: -1.5 + x = -5.678908346 Solving -1.5 + x = -5.678908346 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 = -5.678908346 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + x = -5.678908346 + 1.5 x = -5.678908346 + 1.5 Combine like terms: -5.678908346 + 1.5 = -4.178908346 x = -4.178908346 Simplifying x = -4.178908346Solution
The solution to the problem is based on the solutions from the subproblems. x = {7.178908346, -4.178908346}
