Answer:
{0, 8/5}
Step-by-step explanation:
Please present this 5r2 - 8r =0 as 5r^2 - 8r = 0 or as 5r² - 8r = 0.
Factoring out the r, we get r(5r - 8) = 0.
Setting each factor = 0 separately and finding r in each case, we get:
r = 0 and
5r = 8, so that r = 8/5.
The roots of this polynomial equation are {0, 8/5}.
