1 - Calcule os seguintes limites.
[pic] ► (1² + 4)/ (1+3) = 1+4 / 4 = 5/4
[pic]► (8 – 4 + 4)/(1 - 8) = 8 /(-7 ) = -8/7
[pic] ► (x – 2 ).(x² + 2x + 4) / (x – 2) = (x² + 2x + 4) = 4+ 4+ 4=12
[pic] ► {2 - √(4 –x)}/ x
[pic] ► (y + 2). (y² -2y + 4)/ (y + 2) = (y² - 2y + 4) = 4 + 4 + 4= 12
[pic] ► ∆ = 9 – 8 = 1 x’ = (3 – 1)/ 2 = 1 x” = (3 + 1)/ 2 = 2
(x – 1).(x – 2)/ 2.(x – 1) = (x – 2)/ 2 = (1 – 2)/ 2 = -1/2
[pic] ► ∆ = 9 + 40 = 49 x’= (- 3 – 7)/ 2 = -5 x”= (-3 + 7)/ 2 = 2
► ∆ = 1 + 48 = 49 x’ = (1 – 7)/ 2.2 = -3/2 x” = (1 + 7)/ 4 = 2
(x + 5).(x – 2)/2.(x – 2).(x + 3/2) = (2 + 5)/2.2 + 3 = 7/7 = 1

[pic] ► ∆ = 25 – 24 = 1 t’ = (-5 -1)/2 = -3 t” = (-5 + 1) = -2
(t+3).(t+2)/(t+2) = t + 3 = 2 + 3 = 5
[pic] ► ∆ = 25 – 24 = 1 t’ = (5 -1)/2 = 2 t” = (5 + 1) = 3
(t - 3).(t - 2)/(t -
