What number is represented by −3x²+√2x+1/2 when x=√2?

at x = ,   = -3.5

Step-by-step explanation:

The given equation is

Now, substitute the value of x = in the above equation.

The given equation simplifies to,

now,

So, the equation become

-3(2) + 2 + (1/2) =  

= -3.5

So, at x = ,   = -3.5
