Question

factorize 4y sq + 5 y + 1​

Answer 1

answer:

(4y+1)(y+1)

explanation:

4y^2+5y+1 can also be written as :

4y^2+ 4y + y + 1   --------> [5y = 4y + y]

then by grouping we get :

4y(y+1) + 1(y+1) -------> in 1(y+1)  nothing except 1 is common, hence we take 1.

now we get :

(4y+1)(y+1)
