This is a difference of squares because the number in front of x2 is a perfect square and the constant, 9, is also a perfect square. Just take the square root of both numbers and write it as follows                                          ...

n/6-3n+10 n=-6 (answer)

Everywhere you see an "n", replace it with a -6, so -6/6 - 3(-6) + 10 -1    + 18     + 10 27

First factor out the n and a 8 because n and 8 go into each part. This gives you 8n (3n2 - 5n + 9). Always look for a common factor you can get rid of. The quadratic inside the parenthesis does not factor so this is your final answer.

Okay, first, let's get the z/6 by itself so we need to get rid of the -11. Add -11 to both sides to get z/6 = 11 Now, to get rid of the denominator you need to undo division by 6. The opposite of division by 6 is multiplication by 6. Let's undo the division by 6 by multiplying both sides...

What we want to do here is first check to see if the problem is organized where terms that have common factors are together. This problem meets that criteria because the first 2 terms have x and the 3rd and 4th terms have y in them. Next, we write what both have in common first, so x You...
