Answer:

(x-8)(x+3)

Explanation:

you could use the formula:

(a-b)(a+b)=a^2+b^2

Double checking our work:

(x-8)(x+3)

x^2+3x-8x-24

x^2-5x-24

Given a quadratic polynomial


x^2-5x-24

Using factorization method


\begin{gathered} x^2-8x+3x-24 \\ (x^2-8x)+(3x-24) \\ \end{gathered}

factor out the common factor


\begin{gathered} x(x-8)+3(x-8) \\ we\text{ have} \\ (x-8)(x+3) \end{gathered}

The final answer


x^2-5x-24=(x-8)(x+3)
