How to multiply variables in algebra? What is 2x times x? When multiplying variables in algebra which are the same, you can solve it by adding the exponents. So for example, 2x times x, the answer would be 2x^2. Note that x by itself is actually to the power 1. Likewise the coefficients (the numbers before the variables) can be multiplied ...

In this video, we’ll walk through how to solve the expression 2x times 2x, or 2x multiplied by 2x. This type of problem is common in algebra and easier than it might seem. First, remember that 2x means "2 times x." So when we multiply 2x by 2x, we handle the numbers and variables separately. Start by multiplying the numbers: 2 times 2 gives ...

We simplify and break down the 2 times tables so kids and toddlers can understand more easily, knowing and remembering the tables is the key but knowing the foundations are also critical.

To expand and simplify (x + 2)^2 we can think of this as (x + 2)(x + 2). We then can first multiply x by (x + 2) and then multiply 1 by (x + 2). After that we can combine any like terms to simplify. We are essentially using the distributive property to expand and simply (x + 2)(x + 2). Often the FOIL method is used to help students remember ...
