Question

2. Determina: limx→1/2
[4x2
-8x +1] / [2x2 + x -5] =

1
2
+
1
2
=
2
2
= 1 1
2 /22 = 1/4

= limx→1/2
[4x2 – 8x +1] / limx→1/2

[2x2 + x -5]

= 4 (1/2)2
- 8(1/2) + 1 / 2(1/2)2 + 1/2 -5
= 4(1/4) - 4 + 1 / 2(1/4) + 1⁄2 -5
= 1 – 4 +1 / 1⁄2 + 1⁄2 -5
= -2 / -4
= 1/2

Answer 1

escribe mejor el problema. así no se entiende
