Answer 2

i think this would be simplified to

Answer 3

i think this would be simplified to \[x^2+ax+\pi/2=0\]

Answer 4

now how to solve further?

Answer 5

should i apply b^2-4ac>=0

Answer 6

bu the answer is not coming correct if i apply it!!!

Answer 9

What you have given is an expression. I cannot seen why an expression has a solution.

Answer 10

Should there be another condition that \[x ^{2}-4x+5\le1 \] ie x=2.
Thus a=-8-pi/4
