which are factors of $x^{2}-4x - 5$? select two options.\n$(x - 5)$\n$(x - 4)$\n$(x - 2)$\n$(x + 1)$\n$(x + 5)$

Answer

Explanation:

Step1: Factor the quadratic expression

We need to factor $x^{2}-4x - 5$. We look for two numbers that multiply to $-5$ (the constant term) and add up to $-4$ (the coefficient of the $x$ - term). The numbers are $-5$ and $1$ since $(-5)\times1=-5$ and $-5 + 1=-4$. So, $x^{2}-4x - 5=(x - 5)(x+1)$.

Answer:

A. $(x - 5)$, D. $(x + 1)$
