Answer from: Quest
x = -4
step-by-step explanation:
- 20 - 4(x + 3) = 4x
=> -20 - 4x - 12 = 4x
=> - 32 -4x = 4x
=> -32 = 4x + 4x
=> - 32 = 8x
=> -32/8 = x
=> -4 = x

Answer from: Quest
Prove that every odd prime number can be written as a difference of two squares.prove also that this presentation is unique.is such presentation possible if p is just an odd natural number? can 2 be represented this way?
answers
\3. yes the presentation (i.e. odd numbers being written as differences of two squares) is possible for all odd natural number however the presentation may not be unique. for example, 57=112−82=292−28257=112−82=292−282.
\4. 2 can't be written as a difference of two squares because 4-1=3 and 1-1=0 and the difference of squares grows to integers larger that 3.
can i get some in proving questions 1 and 2?

Answer from: Quest
all of them are elements inside set of real numbers since none of them appears to have complex number form.
hope this .
