Question 1: Factorize $4 x^2{}- y^{2}-2y-1$

How to factorize ?

Solution:

Given expression is

$4 x^2{}- y^{2}-2y-1$

$= 4 x^{2}-(y^{2}+2y+1)$

$= (2x)^{2}-[y^{2}+2(y)(1)+(1)^{2}]$

$= [(2x)^{2}-(y+1)^{2}]$

This now in $a^{2}-b ^{2}=(a+b)(a-b)$

where,

2x stands for a

and

(y+1) stands for b

So, according to this formula;

$=(2x-y-1)(2x+y+1)$
