Answer:
8(3j -2)
4(6j -4)
Step-by-step explanation:
24j - 16
Rewriting
8*3*j - 8*2
Factor out the greatest common factor
8(3j -2)
We can also factor out 4
4*6j - 4*4
4(6j -4)
4a^4 -2b^2 +40
a=2
b=7
4(2)^4 -2(7)^2 +40
PEMDAS is what your gonna use to solve this you go from right to left
First is P which is parentheses which is none
second is E which stands for exponents
4(32)-2(49)+40
now MD multiply or divide
128-98+40
now add or subtract
30+40
last one
70 this is your answer i hope
