Explain : special products of binomials and you

There are different types of special products from binomials. 

One is multiplying a binomial by itself, which would be like . That can be easily reduced to (a+b)(a+b) and then distributed out by FOIL. 

Another would be multiplying a subtract by a subtract. Like . That can be reduced to (a-b)(a-b) and then FOILed out. 

And the last one would be the difference of squares. It's called that because (a+b)(a-b) can be FOILed out to be . And that is a difference of squares. 

Comment if you still have any other questions :)

I'm just guessing, but my answer would c. 0 to 300.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
