Simplifying (x + 7)(x + 7) + 80 = 0 Reorder the terms: (7 + x)(x + 7) + 80 = 0 Reorder the terms: (7 + x)(7 + x) + 80 = 0 Multiply (7 + x) * (7 + x) (7(7 + x) + x(7 + x)) + 80 = 0 ((7 * 7 + x * 7) + x(7 + x)) + 80 = 0 ((49 + 7x) + x(7 + x)) + 80 = 0 (49 + 7x + (7 * x + x * x)) + 80 = 0 (49 + 7x + (7x + x2)) + 80 = 0 Combine like terms: 7x + 7x = 14x (49 + 14x + x2) + 80 = 0 Reorder the terms: 49 + 80 + 14x + x2 = 0 Combine like terms: 49 + 80 = 129 129 + 14x + x2 = 0 Solving 129 + 14x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-129' to each side of the equation. 129 + 14x + -129 + x2 = 0 + -129 Reorder the terms: 129 + -129 + 14x + x2 = 0 + -129 Combine like terms: 129 + -129 = 0 0 + 14x + x2 = 0 + -129 14x + x2 = 0 + -129 Combine like terms: 0 + -129 = -129 14x + x2 = -129 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 = -129 + 49 Reorder the terms: 49 + 14x + x2 = -129 + 49 Combine like terms: -129 + 49 = -80 49 + 14x + x2 = -80 Factor a perfect square on the left side: (x + 7)(x + 7) = -80 Can't calculate square root of the right side. The solution to this equation could not be determined.
