Simplifying t2 + 4t + 8 = 0 Reorder the terms: 8 + 4t + t2 = 0 Solving 8 + 4t + t2 = 0 Solving for variable 't'. Begin completing the square. Move the constant term to the right: Add '-8' to each side of the equation. 8 + 4t + -8 + t2 = 0 + -8 Reorder the terms: 8 + -8 + 4t + t2 = 0 + -8 Combine like terms: 8 + -8 = 0 0 + 4t + t2 = 0 + -8 4t + t2 = 0 + -8 Combine like terms: 0 + -8 = -8 4t + t2 = -8 The t term is 4t. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4t + 4 + t2 = -8 + 4 Reorder the terms: 4 + 4t + t2 = -8 + 4 Combine like terms: -8 + 4 = -4 4 + 4t + t2 = -4 Factor a perfect square on the left side: (t + 2)(t + 2) = -4 Can't calculate square root of the right side. The solution to this equation could not be determined.
