Final answer:
To find a nontrivial solution of ax=0, we need to solve the given equation a + 2b = c. We can choose any values for a and b that satisfy the equation to obtain a nontrivial solution.
Step-by-step explanation:
To find a nontrivial solution of ax=0, we need to solve the given equation. In the equation, it states that the first column plus twice the second column equals the third column.
Let's assume the first column is represented by a, the second column is represented by b, and the third column is represented by c. Based on the given information, we have the equation a + 2b = c.
For a nontrivial solution, we can choose any values for a and b that satisfy the equation. For example, let's say a = 1 and b = 2. Substituting these values into the equation, we get 1 + 2(2) = 5. Therefore, the nontrivial solution is a=1, b=2, and c=5.
