The solution of 2x² - 6x = 0 when?
- x∈0{3}
- x∈0{0}
- x∈W is {0, 3}
- All of these
Explanation
Step 1: Factor the equation
Factor out
from both terms to get:
Set each factor equal to zero to find the solutions:
leads to
leads to
The solutions are
and
. The notation
x∈W is {0, 3}means that the solutions are 0 and 3, and they are elements of the set of whole numbers (W), which is true. Related MCQs
