Simplifying (x + -6)(x + -6) = -6 Reorder the terms: (-6 + x)(x + -6) = -6 Reorder the terms: (-6 + x)(-6 + x) = -6 Multiply (-6 + x) * (-6 + x) (-6(-6 + x) + x(-6 + x)) = -6 ((-6 * -6 + x * -6) + x(-6 + x)) = -6 ((36 + -6x) + x(-6 + x)) = -6 (36 + -6x + (-6 * x + x * x)) = -6 (36 + -6x + (-6x + x2)) = -6 Combine like terms: -6x + -6x = -12x (36 + -12x + x2) = -6 Solving 36 + -12x + x2 = -6 Solving for variable 'x'. Reorder the terms: 36 + 6 + -12x + x2 = -6 + 6 Combine like terms: 36 + 6 = 42 42 + -12x + x2 = -6 + 6 Combine like terms: -6 + 6 = 0 42 + -12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-42' to each side of the equation. 42 + -12x + -42 + x2 = 0 + -42 Reorder the terms: 42 + -42 + -12x + x2 = 0 + -42 Combine like terms: 42 + -42 = 0 0 + -12x + x2 = 0 + -42 -12x + x2 = 0 + -42 Combine like terms: 0 + -42 = -42 -12x + x2 = -42 The x term is -12x. Take half its coefficient (-6). Square it (36) and add it to both sides. Add '36' to each side of the equation. -12x + 36 + x2 = -42 + 36 Reorder the terms: 36 + -12x + x2 = -42 + 36 Combine like terms: -42 + 36 = -6 36 + -12x + x2 = -6 Factor a perfect square on the left side: (x + -6)(x + -6) = -6 Can't calculate square root of the right side. The solution to this equation could not be determined.
