When you divide a variable with an exponent by a variable with an exponent, you subtract the exponents (only if the bases/variables are the same)
For example:
Since they have different variables (x and y), you can't simplify this anymore
( if the exponent happens to come out negative, you have to move the variable and the exponent to the other side of the fraction to make the exponent positive)
Ex:
SInce they all have a common factor of 4, you can divide out -4
If you follow the steps from ^^^^^^^, you should get
Make a triangle with a 90° angle
and another two angles at 45°angles
that's how you make a special right triangles
Answer:
Step-by-step explanation:
A third degree polynomial has a <em>total of three roots</em>, real and imaginary combined.
If it already has 2 real roots, -4 and +4, then it has to have three real roots because imaginary roots come in conjugate pairs, i.e. they come in even numbers.
Answer:
you should not be cheating on a test or your diagnostic ;)
