6x²+x²-6
If 6x=a
and x=b
then using formula
(a²+b²-6)
(a²+b²)-6
(a+b)²-2ab
(6x+x)²-2(6x.x)
36x²+x²-12x²
25x² ans
If 6x=a
and x=b
then using formula
(a²+b²-6)
(a²+b²)-6
(a+b)²-2ab
(6x+x)²-2(6x.x)
36x²+x²-12x²
25x² ans
= 0 is not given
but in factorization we use zero
it is wrong
sry i have done
sry this ans is wrng bcoz i foget to add -6
sry i will do it here awk
25x²-6 then x²=6/25 then x=√6/√25

Solution :
6x² + x² - 6
= 7x² - 6
= ( √7x )² - ( √6 )²
= ( √7x + √6 )( √7x - √6 )
•••••
6x² + x² - 6
= 7x² - 6
= ( √7x )² - ( √6 )²
= ( √7x + √6 )( √7x - √6 )
