Question

factorise √2x2 + x- 3√2=0​

Answer 1

2√2-3√2+x=0

As seen here the first two terms of this expression can be simplified as follows:

2√2-3√2=-1√2

and in the question, the addition of all terms is given as 0

So,

-√2+x=0

add √2 to both sides,

So,

-√2+√2+x=0+√2

x=√2

Answer 2

Answer:  √2 x 2 + x-3√2=0

2√2+x-3√2=0

x+2√2-3√2=0

x+√2(2-3)=0

x+√2(-1)=0

x-√2=0

x=√2
