Question

What is 3x * -x yefowe

Answer 1

Answer:

-$3x^{2}$

Step-by-step explanation:

-x= -1x. (The 1 is invisible)

Now lets do the 3*-1= -3

You still have both of the x's.

All you do is add them. 1+1=2

So, your exponent is going to be 2 with x attached

***When you are multiplying and you have the same exponent, add them. Pretend that you see the exponent 1 by the x ($x^{1}$) now since you have 2 ($x^{1} +x^{1}$) which equals ($x^{2}$)

Looks Like:

3x* -x

=3x* -(1)x

= $-3x^{2}$

Hope this helped :)
