Answer:
8x^2+3x
Step-by-step explanation:
What I read is 2x+8x^2-4x+5x
combining like terms means putting the terms that have the same variable part together
8x^2 is the only one that doesn't have any terms like it as far as the variable part
so 8x^2+2x-4x+5x
We just need to figure out 2-4+5 which is -2+5=3
So the answer is 8x^2+3x
Answer:
The factored form is:

Step-by-step explanation:
The given expression is:

The Greatest Common Factor is 4:
We factor the GCF to get

We rewrite the expression within the parenthesis as difference of two squares.

Recall that: a²-b²=(a-b)(a+b)
This implies that

The middle is zero to the left starting at one go to -5 or whatever the lines stop at (don't forget those are the negative).
Then for the right do the same but positive.
is it missing any details?
