Answer:

y = x^2 - 4x - 6.

Step-by-step explanation:

The roots are  2 + √10 and 2 - √10, so in factor form we have:

(x -  (2 + √10))(x - (2 - √10))

= ( x -  2 - √10)(x - 2 + √10)

= x^2 - 2x + √10x - 2x + 4 - 2√10 - √10x  + 2√10 - √100

=  x^2 -4x + 4 - 10

= x^2 - 4x - 6.

Standard deviation,

= 1.4

ME,

= 0.3

As we know,

⇒ n=(Z \frac{a}{2}\times \frac{SD}{E})^2

On putting the estimated values, we get

⇒    =(2.17\times \frac{1.4}{0 .3})^2

⇒    =(\frac{3.038}{0.3})^2

⇒    =102.5494 \sim 102
