Let's simplify the given expression step by step:
Expand the expression:(x^2 - 7)^2 - 4(x^2 - 7) - 45= (x^2 - 7)(x^2 - 7) - 4(x^2 - 7) - 45= (x^4 - 14x^2 + 49) - 4x^2 + 28 - 45= x^4 - 14x^2 + 49 - 4x^2 - 17
Combine like terms:x^4 - 18x^2 + 32
Therefore, the simplified expression is:x^4 - 18x^2 + 32
I hope that helps! Let me know if you need any further assistance.

= (x^2 - 7)(x^2 - 7) - 4(x^2 - 7) - 45
= (x^4 - 14x^2 + 49) - 4x^2 + 28 - 45
= x^4 - 14x^2 + 49 - 4x^2 - 17
