## Transcript

we are going to factor this out we have 3x squared y square minus 23 XY to a third power plus 30 y to a fourth power as usual we'll see if it is any common factor that we can factor out first let's do Claddagh numbers we have three twenty three and thirty can we think about any common numbers that goes into these numbers no right and you see that f...

## Questions & Answers

### Q: What is the first step in factoring the given polynomial?

The first step is to identify a common factor, which in this case is y^2.

### Q: How does factoring out y^2 affect the other terms in the polynomial?

Factoring out y^2 results in (3x^2 - 23xy + 30y^2), where the exponent of y in each term decreases by 2.

### Q: How can the polynomial be further factored?

The polynomial can be factored using the distributive property as (3x - 5y)(x - 6y).

### Q: Why is the combination of -5y and -6y the correct choice?

The combination of -5y and -6y is the correct choice because they multiply to give -30y^2, which matches the last term in the polynomial. Additionally, their coefficients (-5 and -6) add up to -11xy, matching the middle term.

## Summary & Key Takeaways
