On a study guide! ! what is the value of x? 6m + 3 = 2m - 4 / 2

6m+3=2m-4/2

6m+3=2m-2         divide 4/2

4m+3=-2               subtract 2m from right side and subtract it from 6m

4m=-5                  subtract 3 from right side and from -2

4m/4=5/4           divide to isolate m

m=1.25

hope it helps!

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.
