Question

evaluate : a. limit x tends to 2 x^3 - 2x^2 / x^2 - 5x+6

b. limit x-> 5 x^2 -9x+20 / x^2 - 6x +5

c. limit x-> 1/2 4x^2 -1/2x-1

limit x->root 2 x^2 -2 / x^2 + root 2x -4

​

Answer 1

Answer:

a) =2 c=-1 d) 1

Step-by-step explanation:

a ) lim x tends to 2

x³-2x²/x² -5x +6

x³-2-5x+6

x³-5x+4

apply the limit

(2)³-5(2)+4

8-10+4

12-10=2

c) limit x-> 1/2 4x²-1/2x -1

4(1/2)²-1/2(1/2)-1

4×1/4 -1/2×1/2 -1

1-1-1

=-1

d) limit x -> √2 2x²-2/x² +√2x-4

2(√2)²-2/(√2)² +√2×√2 -4

4 -1+2-4
