1/2x^2-5x+2 when x = 2/3
1/2(2/3)^2 - 5(2/3) + 2 =
1/2(4/9) - 10/3 +2 =
2/9 - 30/9 + 18/9 =
-10/9 =
-1 1/9

x = 2/3
1/2x² - 5x + 2 =
1/2(2/3)² - 5(2/3) + 2
1/2(4/9) - 10/3 + 2
4/18 - 10/3 + 2
2/9 - 10/3 + 2
2/9 - 30/9 + 18/9
- 28/9 + 18/9
- 10/9

1/(2x^2-5x+2)
=1/(x-2)(2x-1)
=1/(2/3 -2)(4/3 -1)
=1/(-4/3)(1/3)
=1/(-4/9)
=-9/4
= -2 1/4
