José works for a company that manufactures components for hand-held game systems. His team has been challenged to reduce the weight of a game system’s faceplate by One-half. It currently weighs Three-fourths of an ounce. What steps could be included in the process as José determines how much the new system should weigh? Check all that apply. Multiply Three-fourths by One-half. Find that Three-fourths × One-half = Three-eighths. Find a common denominator. Find that Three-fourths × One-half = Four-sixths. Add Three-fourths + One-half.

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.
