Simplifying t2 + -9t + 36 = 0 Reorder the terms: 36 + -9t + t2 = 0 Solving 36 + -9t + t2 = 0 Solving for variable 't'. Begin completing the square. Move the constant term to the right: Add '-36' to each side of the equation. 36 + -9t + -36 + t2 = 0 + -36 Reorder the terms: 36 + -36 + -9t + t2 = 0 + -36 Combine like terms: 36 + -36 = 0 0 + -9t + t2 = 0 + -36 -9t + t2 = 0 + -36 Combine like terms: 0 + -36 = -36 -9t + t2 = -36 The t term is -9t. Take half its coefficient (-4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. -9t + 20.25 + t2 = -36 + 20.25 Reorder the terms: 20.25 + -9t + t2 = -36 + 20.25 Combine like terms: -36 + 20.25 = -15.75 20.25 + -9t + t2 = -15.75 Factor a perfect square on the left side: (t + -4.5)(t + -4.5) = -15.75 Can't calculate square root of the right side. The solution to this equation could not be determined.
