Simplifying x2 + -6x + 104 = 4 Reorder the terms: 104 + -6x + x2 = 4 Solving 104 + -6x + x2 = 4 Solving for variable 'x'. Reorder the terms: 104 + -4 + -6x + x2 = 4 + -4 Combine like terms: 104 + -4 = 100 100 + -6x + x2 = 4 + -4 Combine like terms: 4 + -4 = 0 100 + -6x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-100' to each side of the equation. 100 + -6x + -100 + x2 = 0 + -100 Reorder the terms: 100 + -100 + -6x + x2 = 0 + -100 Combine like terms: 100 + -100 = 0 0 + -6x + x2 = 0 + -100 -6x + x2 = 0 + -100 Combine like terms: 0 + -100 = -100 -6x + x2 = -100 The x term is -6x. Take half its coefficient (-3). Square it (9) and add it to both sides. Add '9' to each side of the equation. -6x + 9 + x2 = -100 + 9 Reorder the terms: 9 + -6x + x2 = -100 + 9 Combine like terms: -100 + 9 = -91 9 + -6x + x2 = -91 Factor a perfect square on the left side: (x + -3)(x + -3) = -91 Can't calculate square root of the right side. The solution to this equation could not be determined.
