Question

Simplify as far as possible
(49y^(2)-1)/(7y^(2)+13y-2)

Answer 1

3/13y=0

1) 49y^2-1/7y^2-2

2) 7-1/13y-2

3)3/13y=0

Answer 2

Answer:

$(49 {y}^{2} - 1)(7y {}^{2} + 13y - 2) \\ ({(7y {}^{} ) {}^{2} - 1 {}^{2} })(7y {}^{2} + 14y - y - 2) \\ (7y + 1)(7y - 1) \: \: \: \: \: \: \: (7y(y + 2) - 1(y + 2)) \\ (7y + 1)(7y - 1) \: (7y - 1)(y + 2)$

Hence the result
