Hey there,
2 - 8x + 4x + 4
2 - 8(3) + 4(3) + 4
2 - 24 + 12 + 4
-6
Hope this helps :))

8+4p+2q+r=0
27+9p+3q+r=0
64+16p+4q+r=0
P=-9
Q=26
R=-24
The exponent for that would be 13^3.
If the answer is incorrect, then i am sorry.
The correct answer of

if x=4 is 272.
to solve the equation if x equals 4, you must substitute the x of the 4.

then solve by order of operations.
solve what is inside the parentheses first

then do the multiplication of the factors

then the final step, adding, to get the solution of 272
