Simplifying (x + -6)(x + -6) = -49 Reorder the terms: (-6 + x)(x + -6) = -49 Reorder the terms: (-6 + x)(-6 + x) = -49 Multiply (-6 + x) * (-6 + x) (-6(-6 + x) + x(-6 + x)) = -49 ((-6 * -6 + x * -6) + x(-6 + x)) = -49 ((36 + -6x) + x(-6 + x)) = -49 (36 + -6x + (-6 * x + x * x)) = -49 (36 + -6x + (-6x + x2)) = -49 Combine like terms: -6x + -6x = -12x (36 + -12x + x2) = -49 Solving 36 + -12x + x2 = -49 Solving for variable 'x'. Reorder the terms: 36 + 49 + -12x + x2 = -49 + 49 Combine like terms: 36 + 49 = 85 85 + -12x + x2 = -49 + 49 Combine like terms: -49 + 49 = 0 85 + -12x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-85' to each side of the equation. 85 + -12x + -85 + x2 = 0 + -85 Reorder the terms: 85 + -85 + -12x + x2 = 0 + -85 Combine like terms: 85 + -85 = 0 0 + -12x + x2 = 0 + -85 -12x + x2 = 0 + -85 Combine like terms: 0 + -85 = -85 -12x + x2 = -85 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 = -85 + 36 Reorder the terms: 36 + -12x + x2 = -85 + 36 Combine like terms: -85 + 36 = -49 36 + -12x + x2 = -49 Factor a perfect square on the left side: (x + -6)(x + -6) = -49 Can't calculate square root of the right side. The solution to this equation could not be determined.
