Steve determines line DK and line BC are congruent. He also measures angle K and angle C and determines they are congruent. He concludes that the triangles are congruent by SAS congruence theorem. Is steve correct? If he is incorrect, which congruence theorem should steve use? Explain your reasoning and show all of your work including measurement of angles and/or line segments

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.

c
