Answer:
25
Step-by-step explanation:
8b^2 +2a(4c-b)
Let a = 1/4 b=2 c= -3
8 ( 2)^2 +2(1/4) ( 4*-3 -2)
Parentheses first
8 ( 2)^2 +2(1/4) ( -12 -2)
8 ( 2)^2 +2(1/4) ( -14)
Then exponents
8 ( 4) +2(1/4) ( -14)
Then multiply
32 -7
Subtract
-1
substitute x for 6 and y for 1
which will be 6-1+6
using BODMAS
6-(1+6)
6-7= -1
