Question

4y²-4y+1 factorise this​

Answer 1

Answer:

4y²-(2+2)y+1

4y²-2y-2y+1

2y(2y-1)-1(2y-1)

(2y-1) (2y-1)

Answer 2

$\huge\bold{Answer}$

$\bold{4y^2 - 4y + 1}$

$\bold{By \: using \: Identities }$

$\bold{(a-b)^2}$ $\bold{=}$ $\bold{a^2 - 2ab - b^2}</h2><h2>$

$\bold{2y^2 - 2×2y×1 + 1^2}$

$\bold{(2y-1)^2}$

$\bold{(2y-1)}$ $\bold{(2y-1)}$
