Tilly is sewing shades for her windows. Each shade will be 48 inches long and 24 inches wide. The canvas she is buying is sold at 56 inches wide and sold by the yard. If

she is making 10 shades and will keep 4 inches between each tracing of the shade

patterns, what is the most efficient layout to trace the shades on the fabric and how much

fabric should she buy

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

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.

answer: (-6,3)
