Answer:

Step-by-step explanation:
I assume your equation to solve is

When we have a product of two factors equal to zero,

The solution is either A = 0 or B = 0.
In this case, this means that we can break the equation into two equations:

Solving the first one, we get:

For the second one, we rewrite it as:

And we see that this equation has two solutions:

Therefore, the three solutions are:

1. 43,300
2. 568,000
3. 910,000
4. <span>91,00,000,000
