Step-by-step explanation:
Find the multiples of 2x^2 and 2
for 2x^ you get 2,1 but they need to have x to get x^2 so; (2x and x)=2x^2
for 2 you get 2,1 (2x1)=2
Because your equation has a 5x and no negatives you know that your factors need to be positive.
(2x+1)(x+2)
when you multiply these you get
2x^2+4x+x+2 (remember 2x multiplies with everything inside (x+2) = 2x^2+4) and so on for the x (x+2) =x+2 )
Then you combine like terms 4x+x=5x
and those are the only like terms available and you get
2x^2+5x+2
