When you multiply 4x by x, you are essentially multiplying 4 by x and then multiplying the result by x again. This can be written as:
4x × x
To simplify this, you multiply the coefficients (the numbers) and then multiply the variables (the x’s).
First, multiply the coefficients:
4 × 1 = 4
Next, multiply the variables:
x × x = x²
So, when you multiply 4x by x, the result is:
4x²
Therefore, 4x times x equals 4x².
