([5x+10/x^2 ] * [ x/x+2 ] )+ 2/3
(5(x + 2) / x^2 ) * (x / x+2 ) + 2/3
cancel x+2 and x
(5/x * 1 ) + 2/3
5/x + 2/3
take lcm
( 5*3 + 2*x) / 3x
( 15 + 2x )/3x
(2x + 15)/3x

including/subtracting rational fractions and standard fractions, you may desire to have a typical denominator. Dividng/multiplying rational fractions and standard fractions, you opt to do a super number of cancelling, different than with rational fractions you sometimes might desire to element so some distance as available with the intention to cancel out stuff.
