CAN ANYBODY PLS HELP MEEE REAWARD BRAINLIEST

Option C

1.62 and -0.62

Step-by-step explanation:

v² - v - 1 = 0

From ax² + bx + c = 0

a = 1 b = -1 c = -1

Quadratic formula

x = -b +/- √b² - 4ac

2a

x = -(-1) +/- √-1² - 4 x 1 x -1

2(1)

x = 1 +/- √1 +4

2

x = 1 +/- √5/2

x = 1 + √5/2 or x = 1 - √5/2

x = 1.618 or -0.618

step-by-step explanation:

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.
