Answer:
r = 2/ r = -2/3
Explanation:
so you move the terms to the left side
6r^2 - 8r = 8
6r^2 -8r - 8 = 0
the common factor
6r^2 - 8r -8 = 0
2(3r^2 - 4r - 4) = 0
then you divideboth side by the same factor
2(3r^2 - 4r - 4) = 0
3r^2 - 4r - 4 = 0
use the quadratic formula
you would get 2.3
then you simplify
r = 4+8 over 6
seperate the equations
r = 4+8 over 6 change the plus into a minus
after that rearrange and issolate variable
r = 2
r = -2/3
therfore your answer is -2/3
