1)There are 30 apples in one bin. And 20 apples in the other.
What is the total number of apples?

2) Then 15 apples got eaten.
How many are left out of the total apples?

1) 50

2) 35

Step-by-step explanation:

1) 30+20=50

2) 50-15=35

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.
