4=4
4-4=4-4
2²-2²=2²-2²
(2+2)(2-2)=2(2-2)
2+2=2
4=2
what is wrong?

answer:

4=4   = ture

4-4=4-4   = true

2²-2²=2²-2²   = ture

(2+2)(2-2)=2(2-2)   = true

2+2=2   + false

4=2 = false

step-by-step explanation:

answer: f = 32.2m

step-by-step explanation: that is the answer

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.
