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

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
