This is nothing you need to solve, I just need a refresher about this type of math. For some reason I can't remember this right now. Can you please help? So if I have 2x^2 + 1x, isn't there technically an exponent of 1 above the 1x?
(I'm trying to factor and solve the equation: 2x^2 + x - 21 = 0, if that helps.)

Answer and Step-by-step explanation:

As goddesboi mentioned, is the same as x.

Because of this, we don't put the 1 in the exponents place, but if you do, there is nothing wrong with it. This can also be applied to 1 times a number, say for example x. We don't keep the 1 with the x because it is the same thing as saying, x, so it is easier and faster to write.

I hope this helps!
