Question

factroize 4y^2-4y+1 by appropriate identities

Answer 1

(3x + y)2 = (3x + y) (3x + y) Ex 2.5, 3 Factorise the following using appropriate identities: (ii) 4y2 – 4y + 1 4y2 – 4y + 1 = 22 y2 – 4y + 12 = (2y)2 – 4y + 12 ...

Answer 2

4y²‐4y+1 = (2y)²-2(2y)(1)+1²

Using identity 2

= (2y-1)²=(2y-1)(2y-1)
