Simplify 2x + x

o 2x2

3x

O 3x²

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant 2 • 2 = 4

Step-2 : Find two factors of 4 whose sum equals the coefficient of the middle term, which is 3.

-4 + - 1 = - 5

-2 + - 2 = - 4

-1 + - 4 = - 5

1 + 4 = 5

2 + 2 = 4

4 + 1 = 5

Observation : No two such factors can be found!
