What is the factored form of x2 − 4x − 5?


(x + 5)(x − 1)

(x + 5)(x + 1)

(x − 5)(x − 1)

(x − 5)(x + 1)

Verified Answer :

x^ − 4x − 5 = (x - 5)(x+1)
answer is 
(x − 5)(x + 1) (last choice)

Answer:

option (d) is correct.

The factored form of the given equation \(x^2-4x-5\) is \(\left(x+1\right)\left(x-5\right)\)

Step-by-step explanation:

Given : equation \(x^2-4x-5\)

Consider the given equation \(x^2-4x-5\)

We can solve the given equation using middle term splitting method.

Split middle term in such a way that the product of its terms is the product of its remaining two terms.

-4x can be written as x - 5x

\(x^2-4x-5\) can be written as \(x^2+x-5x-5\)

Taking x common from first two term and -5 common from last two terms, we have,

\(x(x+1)-5(x+1)\)

Simplify, we have,

\(\left(x+1\right)\left(x-5\right)\)

Thus, The factored form of the given equation \(x^2-4x-5\) is \(\left(x+1\right)\left(x-5\right)\)
