That is not calculus. x ² + 4 y² - 6 x + 8 y + 9 = 0 Re-group: Subtract 9 to both sides. x ² + 4 y² - 6 x + 8 y = - 9 ( x² - 6 x ) + ( 4 y² + 8 y ) = - 9 ( x² - 6 x ) + 4 ( y² + 2 y ) = - 9 Complete the squares: ( x² - 6 x + 3² ) + 4 ( y² + 2 y
t ₙ = 4 n² n = 1 t ₁ = 4 ∙ 1² = 4 ∙ 1 = 4 n = 2 t ₂ = 4 ∙ 2² = 4 ∙ 4 = 16 n = 3 t ₃ = 4 ∙ 3² = 4 ∙ 9 = 36 n = 4 t ₄ = 4 ∙ 4² = 4 ∙ 16 = 64 n = 5 t ₅ = 4 ∙ 5² = 4 ∙ 25 = 100 n = 6 t ₆ = 4 ∙ 6² = 4 ∙ 36 = 144 n =
