Ok so I have been doing algebra for a few weeks at school but I am off school self iscolating and I dont know how to do the following. any help would be appreciated thanks in advance!!
simplify :
5x^2+15x-25
5x
I think I divide all by 5 but I have no idea why other than it looks good and seems to work ? as 5 15 and 25 all have 5 as a factor ???
