Write an equation of the line in point-slope form, (y-y1=m(x-x1)) slope-intercept form (y=mx+b) and standard form (ax+by=c where a+b are not both zero) that passes through the given 2 points. (1,-2) and (1,-3) (-1,4) and (2,4)

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.
