Answer:
A negative number squared is a positive number. Squaring is multiplying a number by its self.
Step-by-step explanation:
X^2 = x * x
Squaring something is just multiplying it by its self.
A negative times a negative = a positive
A positive times a positive = a positive
A negative times a positive = a negative
A positive times a negative = a negative
- * - = +
+ * + = +

+ * - = -
Here is how my 6th grade teacher helped me to remember it:
If something bad (-) happens to a bad guy (-), that is good.
If something good (+) happens to a good guy (+), that is good.
If something bad (-) happens to a good guy (+), that is bad.
If something good (+) happens to a bad guy (-), that is bad.
I hope I helped!

Answer:
-2/9
Step-by-step explanation:
first you are going to distrubute 2/5, so 2/5 times x is 2/5x and 2/5 times -2 is -4/5
next you set up the problem with those two answers which gives you:
2/5x - 4/5 = 4x
then multiply both sides of the equation by 5: 2x-4=20x
next move the constant to the right side and chnage the sign: 2x=20x+4
then combine like terms: -18x=4
after that divide both sides of the equation by -18: -2/9
so x= -2/9
