Question

correct me if im wrong?
Identify the factors of x2 - 8x - 20.
Answer
(x - 2)(x + 10) I think its this one.
(x + 5)(x - 4)
(x - 10)(x + 2)
(x + 4)(x - 5)

Answer 1

Let me check this one for you.


\(\Large \color{MidnightBlue}{\Rightarrow x(x + 10) - 2(x + 10) }\)
\(\Large \color{MidnightBlue}{\Rightarrow x^2 + 10x - 2x - 20 }\)
\(\Large \color{MidnightBlue}{\Rightarrow x^2 + 8x - 20 }\)

Correcto!
