Question

4a^2 + 4a +1 by 2a+1

Answer 1

let 2a+1=0
so
a=-1/2;

now putting the value of "a" on in 4a^2+4a+1
=》4 (1/4)+4 (-1/2)+1
=》1 - 2+1=0

answer=0
also,
2a+1 is a factor of 4a^2 + 4a+1

Answer 2

4a^2+4a+1/2a+1
Now factorise the denominator
Then get, (2a+1)(2a+1)
2a+1)(2a+1)/2a+1
Now cancel the 2a+1
The Ans is 2a+1
