Answer

$(a + 8)(a + 3)$

Work Step by Step

We have a quadratic equation in the form of $ax^2 + bx + c$, where $a$, $b$, and $c$ are all real numbers. To factor this equation, we want to find which factors when multiplied will give us the product of the $a$ and $c$ terms, which is $24$, but when added together will give us the $b$ term, which is $11$. This means that the two factors must both be positive. Let's look at possible factors: $8$ and $3$ $6$ and $4$ $24$ and $1$ It looks like the first combination will work. Let's rewrite the expression in factored form: $(a + 8)(a + 3)$
