5x^2+11x+2 / 5x+1
5x^2+10x+x+2 / 5x+1
5x(x+2)+1(x+2) / (5x+1)
(5x+1)(x+2) / (5x+1)
cancelling out 5x+1 both in the numerator & denominator
x+2 is the answer

first, simplyfy the numerator: 5x^2 +11x +2
(5x+1)(x+2) --> you have to guess and check to do this part, but you can guess one of the terms is 5x+1 so it will cancel with the denominator
the (5x+1) cancel, and you are left with...
x+2

5x^2+11x+2 / 5x+1 = ( 5x +1 ) ( x +2)/( 5x +1 )
( x +2)

(5x^2+11x+2) /( 5x+1)
= (5x+1)(x+2)/( 5x+1)
= x+2
