To evaluate a–4b^2 for a = –2 and b = 4, substitute these values into the expression:
a – 4b^2
= -2 - 4(4)^2
= -2 - 4(16)
= -2 - 64
= -66
Thus, the value of a–4b^2 when a = –2 and b = 4 is -66.
a – 4b^2
= -2 - 4(4)^2
= -2 - 4(16)
= -2 - 64
= -66
Thus, the value of a–4b^2 when a = –2 and b = 4 is -66.

I apologize for the confusion. Let's reevaluate the expression using the correct values.
To evaluate a–4b^2 for a = –2 and b = 4, substitute these values into the expression:
a – 4b^2
= -2 - 4(4)^2
= -2 - 4(16)
= -2 - 64
= -66
