Simplifying Radicals
In this discussion, you will simplify and compare equivalent expressions written both in radical
form and with rational (fractional) exponents. Read the following instructions in order and view
the example to complete this discussion:
This week I had the letter O, so I had to do number 42 ad 52.
#42 Factoring
y^2-3y-10=0
First, I started by Factoring my equation.
(y+2)(y-5)=0
After, this I took the factors and got this
y+2=0 or y-5=0
Then I used the Zero Factored property
y=-2 or y=5

I started by using the quotient rule, -2/3 (- 1/3) this lead me to get.
27^ (-1/3). After this I needed to get rid of the negative exponent, therefore I made it into the r
I had the problem 16 and 50 since my last name ends with N.

h ( x )=|2 x|
I started with plugging number from -2 thru 2 into the relation to get what my coordinates would
be.

-1 2

2 4
These are the answers that I got

If we join two simple inequalities with the connective and or the connective or, we get a compound
inequality.
