Answer: The answer is a ahahahha thats funny im in 8th grade and i figured that out and we are not even doing that yet its just infering
I'm assuming you want to simplify the expression since it's not equal to anything.. you can't solve for "a" unless it's equal to something.
factor
8a³ - 2a²+ 12a - 3
2a²(4a - 1) + 3(4a -1)
(4a - 1) is a like term that can be combined further.
(2a² + 3)(4a - 1)
563 X 410 = 230830, you're welcome
