What is 2x Squared?

[DeannaFvw]

I’m learning algebra and came across the term 2x Squared. Can someone explain what it represents and how it’s used in equations?

 

[EnidLindt]

The expression 2x squared usually means:

[
2x^2
]

This is read as “two times x squared,” where x is multiplied by itself first, then multiplied by 2.

Example: If (x = 3):
[
2x^2 = 2 \times (3^2) = 2 \times 9 = 18
]


It is not the same as ((2x)^2), which would be (4x^2).

 

[Robert Willian]

The expression `2x^{2}` means a situation wherein \(2\) is multiplied with the square of the variable \(x.\)

 

[Ericasinclair]

“2x squared” means (2x^2), which is 2 times (x) multiplied by itself ((x \cdot x)).

2x squared" means 2x22x^22x2, which is 2 multiplied by the square of xxx. It represents a quadratic term in algebra, not (2x)2(2x)^2(2x)2 unless specified.

2x squared usually refers to the expression 2x², meaning 2 multiplied by x squared. In algebra, you square the variable first (x × x), then multiply the result by 2. It represents a quadratic term commonly used in equations and graphs, forming part of a parabola when plotted. Always check context, since wording can sometimes cause confusion.
