Solve for u

10 - 6u = -8u + 2

u= -4

Step-by-step explanation:

To solve, we need to isolate the variable: u

10-6u= -8u+2

Add 8u to both sides

10-6u+8u=-8u+8u+2

10+2u=2

Subtract 10 from both sides

10-10+2u=2-10

2u=-8

Divide both sides by 2

2u/2= -8/2

u= -4

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.
