Question

Which factored form is equivalent to the expression x^2 + 5x + 4? A) (x + 2)(x + 3) B) (x + 4)(x + 1) C) (x + 5)(x − 1) D) (x − 4)(x + 1)

Answer 1

Answer ↓

option B.

Calculations ↓

First, let's think of two numbers so that :

• if we multiply these numbers, we'll get 4
• if we add these numbers, we'll get 5

These numbers are :

4 and 1

Plug these numbers here :

(x+4) (x+1)

So the correct factored form of this expression is

Option B) (x+4)(x+1)
