Simplifying (x + -4)(x + -4) = 8 Reorder the terms: (-4 + x)(x + -4) = 8 Reorder the terms: (-4 + x)(-4 + x) = 8 Multiply (-4 + x) * (-4 + x) (-4(-4 + x) + x(-4 + x)) = 8 ((-4 * -4 + x * -4) + x(-4 + x)) = 8 ((16 + -4x) + x(-4 + x)) = 8 (16 + -4x + (-4 * x + x * x)) = 8 (16 + -4x + (-4x + x2)) = 8 Combine like terms: -4x + -4x = -8x (16 + -8x + x2) = 8 Solving 16 + -8x + x2 = 8 Solving for variable 'x'. Reorder the terms: 16 + -8 + -8x + x2 = 8 + -8 Combine like terms: 16 + -8 = 8 8 + -8x + x2 = 8 + -8 Combine like terms: 8 + -8 = 0 8 + -8x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-8' to each side of the equation. 8 + -8x + -8 + x2 = 0 + -8 Reorder the terms: 8 + -8 + -8x + x2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -8x + x2 = 0 + -8 -8x + x2 = 0 + -8 Combine like terms: 0 + -8 = -8 -8x + x2 = -8 The x term is -8x. Take half its coefficient (-4). Square it (16) and add it to both sides. Add '16' to each side of the equation. -8x + 16 + x2 = -8 + 16 Reorder the terms: 16 + -8x + x2 = -8 + 16 Combine like terms: -8 + 16 = 8 16 + -8x + x2 = 8 Factor a perfect square on the left side: (x + -4)(x + -4) = 8 Calculate the square root of the right side: 2.828427125 Break this problem into two subproblems by setting (x + -4) equal to 2.828427125 and -2.828427125.Subproblem 1
x + -4 = 2.828427125 Simplifying x + -4 = 2.828427125 Reorder the terms: -4 + x = 2.828427125 Solving -4 + x = 2.828427125 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = 2.828427125 + 4 Combine like terms: -4 + 4 = 0 0 + x = 2.828427125 + 4 x = 2.828427125 + 4 Combine like terms: 2.828427125 + 4 = 6.828427125 x = 6.828427125 Simplifying x = 6.828427125Subproblem 2
x + -4 = -2.828427125 Simplifying x + -4 = -2.828427125 Reorder the terms: -4 + x = -2.828427125 Solving -4 + x = -2.828427125 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + x = -2.828427125 + 4 Combine like terms: -4 + 4 = 0 0 + x = -2.828427125 + 4 x = -2.828427125 + 4 Combine like terms: -2.828427125 + 4 = 1.171572875 x = 1.171572875 Simplifying x = 1.171572875Solution
