7√2 x^2 – 14x + 4x – 4√2 = 0
7√2 x ( x – √2 ) + 4 ( x – √2 ) = 0
so, ( 7√2x + 4 ) ( x – √2 ) = 0
so, 7√2x + 4 = 0 and
x – √2 = 0
that is x = –4 / 7√2 so x =(–2√2 / 7)
and also x= (√2)
both are answers
hope it helps
you can comment ur problem if u didn't understand
AryanKaushk:
why 14x-4x
+4x
it is –14x + 4x so that we get –10x
yeah but how did u choose as -14x+4x
bcoz product of 7√2 and 4√2 = 56
so
so now we have to factorise 56 in such a way so that
thanks
if we adding numbers we get –10 and by multiplying we get 56.that's it
ok bro
