What number is represented by −3x²+√2x+1/2 when x=√2?
Mila [183]

Answer:

at x = \sqrt{2},  -3x^{2} + \sqrt{2}x + \frac{1}{2} = -3.5

Step-by-step explanation:

The given equation is -3x^{2} + \sqrt{2}x + \frac{1}{2}

Now, substitute the value of x = \sqrt{2} in the above equation.

The given equation simplifies to,

-3(\sqrt{2})^{2} + (\sqrt{2})(\sqrt{2}) + \frac{1}{2}

now, \sqrt{2} . \sqrt{2}  = 2, \textrm{and} (\sqrt{2} )^{2} = 2

So, the equation become

-3(2) + 2 + (1/2) = -6 + 2 + \frac{1}{2}   = -4 + \frac{1}{2} = \frac{-8 + 1}{2}  = \frac{-7}{2}  

= -3.5

So, at x = \sqrt{2},  -3x^{2} + \sqrt{2}x + \frac{1}{2} = -3.5
