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

AryanKaushk: +4x

aryan6414: it is –14x + 4x so that we get –10x

AryanKaushk: yeah but how did u choose as -14x+4x

aryan6414: bcoz product of 7√2 and 4√2 = 56

AryanKaushk: so

aryan6414: so now we have to factorise 56 in such a way so that

AryanKaushk: thanks

aryan6414: if we adding numbers we get –10 and by multiplying we get 56.that's it

AryanKaushk: ok bro
