Error Analysis: Which statement best describes the error in finding the distance between the points (7,5) and (-2, 1)?
AB = V(202 – 21)2 + (y2 – yı)?
AB 117 - 5)2 +(-2 - 1)
AB=
22+(-3)
AB = 14 + 9
AB = V13
AB 3.6
The formula is incorrect.
There is an error identifying the 2- and y-values to subtract.
There is a subtraction error.
The square root was calculated incorrectly.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
