Here is the problem that I need to solve:

y = ab - ac ² (that is a second power symbol if you can't tell).
I need to solve the problem for a.

Thank you!

If you really mean that only c is squared then

a = y/(b-c^2)

Thank you so much! I think I get it now.

To solve this problem for 'a', we need to isolate 'a' on one side of the equation. Let's step-by-step solve the equation:

1. Start with the given equation: y = ab - ac².
2. Group the terms that contain 'a' together: y = a(b - ac²).
3. Next, divide both sides of the equation by (b - ac²) to isolate 'a'. This will give us: y / (b - ac²) = a.

Therefore, by dividing both sides of the equation by (b - ac²), we can solve for 'a', and the resulting equation is a = y / (b - ac²).
