Unfortunately, the browser used for posting questions does not accept most mathemetical symbols so it is not posible to answer the question as it appears. Please resubmit it using words, such as "plus", "minus", "to the power". Also, use open and closed brackets or parentheses since x plus y squared could mean x + y2 or (x + y)2.
No. A factored form of one can not be used here.

Yes.
35x - 21 We note that '35' & '21' are both multiples of '7' ; (7 x 5 = 35 & 7 x 3 = 21). So seven is factored out. 7(5x - 3)
x2+10x+21 = (x+3)(x+7) when factored.....

If that's + 21, the answer is (n - 3)(4n -7)
Yes.

7 and (-3/2)

For the sum being 22X + Y = 22X and Y can be a range of different numbers, such as 1+21, 2+20, 3+19 and so on.For the difference being 20X - Y = 20If you'd fill in the ranges of numbers above, you'd get 21-1=20, 20-2=18, 19-3=16 and so on.X must be 21 and Y must be 1.21+1=2221-1=20
21/5 is the simplest form.
2/21 is in its simplest form.2/21 is in its simplest form.
21/50 is in its simplest form.
