The image contains the expression $(6a + 5)(5a - 6)$. Let's expand and simplify it.

Step-by-step solution:

We use the distributive property (also known as FOIL for binomials) to expand the product:

$(6a + 5)(5a - 6)$

Multiply each term in the first binomial by each term in the second binomial:

1. $6a \times 5a = 30a^2$
2. $6a \times -6 = -36a$
3. $5 \times 5a = 25a$
4. $5 \times -6 = -30$

Now, combine the results:

$30a^2 - 36a + 25a - 30$

Combine the like terms $-36a + 25a$:

$30a^2 - 11a - 30$

Final answer:

$30a^2 - 11a - 30$
