Simplifying (x + 7)(x + -4) = 4 Reorder the terms: (7 + x)(x + -4) = 4 Reorder the terms: (7 + x)(-4 + x) = 4 Multiply (7 + x) * (-4 + x) (7(-4 + x) + x(-4 + x)) = 4 ((-4 * 7 + x * 7) + x(-4 + x)) = 4 ((-28 + 7x) + x(-4 + x)) = 4 (-28 + 7x + (-4 * x + x * x)) = 4 (-28 + 7x + (-4x + x2)) = 4 Combine like terms: 7x + -4x = 3x (-28 + 3x + x2) = 4 Solving -28 + 3x + x2 = 4 Solving for variable 'x'. Reorder the terms: -28 + -4 + 3x + x2 = 4 + -4 Combine like terms: -28 + -4 = -32 -32 + 3x + x2 = 4 + -4 Combine like terms: 4 + -4 = 0 -32 + 3x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '32' to each side of the equation. -32 + 3x + 32 + x2 = 0 + 32 Reorder the terms: -32 + 32 + 3x + x2 = 0 + 32 Combine like terms: -32 + 32 = 0 0 + 3x + x2 = 0 + 32 3x + x2 = 0 + 32 Combine like terms: 0 + 32 = 32 3x + x2 = 32 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 = 32 + 2.25 Reorder the terms: 2.25 + 3x + x2 = 32 + 2.25 Combine like terms: 32 + 2.25 = 34.25 2.25 + 3x + x2 = 34.25 Factor a perfect square on the left side: (x + 1.5)(x + 1.5) = 34.25 Calculate the square root of the right side: 5.852349955 Break this problem into two subproblems by setting (x + 1.5) equal to 5.852349955 and -5.852349955.Subproblem 1
x + 1.5 = 5.852349955 Simplifying x + 1.5 = 5.852349955 Reorder the terms: 1.5 + x = 5.852349955 Solving 1.5 + x = 5.852349955 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 = 5.852349955 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = 5.852349955 + -1.5 x = 5.852349955 + -1.5 Combine like terms: 5.852349955 + -1.5 = 4.352349955 x = 4.352349955 Simplifying x = 4.352349955Subproblem 2
x + 1.5 = -5.852349955 Simplifying x + 1.5 = -5.852349955 Reorder the terms: 1.5 + x = -5.852349955 Solving 1.5 + x = -5.852349955 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 = -5.852349955 + -1.5 Combine like terms: 1.5 + -1.5 = 0.0 0.0 + x = -5.852349955 + -1.5 x = -5.852349955 + -1.5 Combine like terms: -5.852349955 + -1.5 = -7.352349955 x = -7.352349955 Simplifying x = -7.352349955Solution
The solution to the problem is based on the solutions from the subproblems. x = {4.352349955, -7.352349955}
