Simplifying x2 + 14x + 65 = 0 Reorder the terms: 65 + 14x + x2 = 0 Solving 65 + 14x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-65' to each side of the equation. 65 + 14x + -65 + x2 = 0 + -65 Reorder the terms: 65 + -65 + 14x + x2 = 0 + -65 Combine like terms: 65 + -65 = 0 0 + 14x + x2 = 0 + -65 14x + x2 = 0 + -65 Combine like terms: 0 + -65 = -65 14x + x2 = -65 The x term is 14x. Take half its coefficient (7). Square it (49) and add it to both sides. Add '49' to each side of the equation. 14x + 49 + x2 = -65 + 49 Reorder the terms: 49 + 14x + x2 = -65 + 49 Combine like terms: -65 + 49 = -16 49 + 14x + x2 = -16 Factor a perfect square on the left side: (x + 7)(x + 7) = -16 Can't calculate square root of the right side. The solution to this equation could not be determined.
