When you see the expression 2x squared, it means you need to square the value of x and then multiply it by 2. Squaring a number means multiplying it by itself. So, if x is 3, then x squared is 3 multiplied by 3, which equals 9. Then, you multiply 9 by 2 to get 18. Therefore, 2x squared is 2 times x squared, or 2(x²). This can be written as 2x². For example, if x = 4, then 2x² = 2(4²) = 2(16) = 32.
