What is 2x times 7x?

2x × 7x = ?

Here we will do more than give you the solution to 2x × 7x. We will also explain and teach you how we came up with the answer, so you can understand it and solve similar problems in the future without help.

In this problem, 2 and 7 are the coefficients and two Xs are the variables. When a coefficient is next to a variable there is an invisible multiplication sign. So you could rewrite the problem as follows:

2 × x × 7 × x =

So now you can multiply what are the same. You can multiply the coefficients together and the x variables together as follows:

2 × 7 = 14

x × x = x²

Then you put the answers together and make the multiplication sign invisible again to get the following answer:

2x × 7x = 14x²

If you multiply two same variables with exponents, you simply keep the variable and add the exponents. Also x with no exponent is the same as x¹.

Here are some problems with answers that you should know based on what you learned on this page:

2x × 7x² = 14x³

2x × 7x³ = 14x⁴

2x × 7x⁴ = 14x⁵

2x² × 7x = 14x³

2x² × 7x² = 14x⁴

2x² × 7x³ = 14x⁵
