Given :-
- 4y² - 4y + 1
Answer :-
The factores of given expression is y = ½
Explaination :-
The identity that can be used to factorize the given expression is:
- (a - b)² = a² - 2ab + b²
Now, using the above identity we get :
→ (2y)² - 2(2y)(1) + (1)² = 0
→ (2 y - 1)² = 0
→ (2y - 1) (2 y - 1) = 0
→ y = ½
