Question

I need to solve it but don't know how

Answer 1

I think it might be 4x^2 + 5x because if you are factoring by GCM, the GCM in this expression would be 2.

Answer 2

We have the expression
`8 x^(2) + 10x`, note that both terms have the factor 2x, if we factor this out, we are left with:

2x(4x + 5)
If you redistribute it you can see that it equals
`8 x^(2) + 10x`

Hope this helps! :)
