14-3(2³-4x2)/10+2[(-3)²-3-(-2)²]
14 -3(8 - 8)/ 10 + 2[9 - 3 - 4}
14 - 3(0) / 10 + 2[2]
14 - 0/10 + 4
14/14
= 1
Hope this helps.

14-3(2³-4x2)/10+2[(-3)²-3-(-2)²]
--------------
= 14 - 3(8-4x^2)/10 + 2[9-3-(4)]
--------------
= 14 -3(4)(2-x^2)/10 + 2[2]
-----
= 14 -(6/5)(2-x^2)+4
----------
Note: That certainly is not "1".
Please check your post.
