Find the value of 5x -10 given that negative 2x +2 equals 8

5

Step-by-step explanation:

Let's solve for x first

2x+2=8

    -2  -2

2x=6

Divide both sides by 2

x=3

Plug into our equation (5x-10)

(5*3)-10=?

15-10=?

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.
