How do you factor 2 x plus 1?

Answer 1

2x + x

(x + x) + x

x + x + x = 3x

2x + x = 3x

No, no, no! The correct answer is:

x2 + x = x(x + 1).

It is sometimes best to test answers with various substitution values.

x2 + x = 3x, only when x = 0 or 2; but not otherwise.

Answer 2

(2x + 1) is as much as you can factor it without resorting to fractions. If you want to get x by itself,

2*(x + 1/2)

Answer 3

x2 + 2x = 3

x2 + 2x - 3 = 0

(x + 3)(x - 1) = 0

x ∈ {-3, 1}

Answer 4

Use the quadratic formula as there are no integer roots.

x2 + 3x + 2 factors as (x + 1)(x + 2) and x2 - 3x + 2 factors as (x - 1)(x - 2)

Answer 5

Short answer: No common factors and no real roots.

Long answer: It can be factored, it just won't be pretty. Any time you're getting into the cube root of -1, it's dangerous territory.

Answer 6

Unless you know the value of X, the only factors of (x+2) that you can identify are itself and one (1)

Answer 7

x + 2 is in its simplest form.

Answer 8

(x + 2)(x + 1)
