Question

Using the identity farctorise the
following a2-b2=(a-b)(a+b) (i)
zy2-50​

Answer 1

Answer:

zy²-50

(

$( { \sqrt{z} \: y })^{2} - ( {5} \sqrt{2} )^{2}$

$( \sqrt{z} \: y - 5 \sqrt{2} )( \sqrt{z} \: y + \sqrt{2} )$

Answer 2

Step-by-step explanation:

As i understand ur question...

$2 {y}^{2} - 50 \\ \\ = 2( {y}^{2} - 25) \\ \\ = 2( {y}^{2} - {5}^{2} ) \\ by \: using \: property \\ ( {a}^{2} - {b}^{2} ) = (a + b)(a - b) \\ \\ = 2(y + 5)(y - 5) \\ \\ requird \: ans....$

This is ur ans.............
