Let's take example first :y^2+9y+20;Now, split third term I mean take two values whose product is 20 and sum is 9y:-so,we can say that , 2y and 10y are 20 but there sum isn't 9y. Now again try, you can take here 4y and 5y whose sum is 9y. Now, A.T.Q:-y^2+9y+20=y^2+4y+5y+20?now factorise. You will get y(y+4)+5(y+4), so take out the common you will get your answer that is (y+4)(y+5).
