1^2 + 1^2 + 1^2 + 1^2 + 1^2 + 1^2 = 1 + 1 + 1 + 1 + 1 + 1 = 5

1 squared (1x1) +3=4
8 + X SQUARED
Yes. 'sin2x + cos2x = 1' is one of the most basic identities in trigonometry.
Cosine squared theta = 1 + Sine squared theta

1 squared plus 8 squared or 4 squared plus 7 squared
B squared -4ac is the discriminant. you get 0, which means it will have one rational solution.
It is the same as: x^2 +2x +1 and it is (x+1)(x+1) when factored
1 squared (1x1) +3=4
1 + cot2x = csc2x
yes 1 + cot x^2 = csc x^2
Yes. 'sin2x + cos2x = 1' is one of the most basic identities in trigonometry.
8 + X SQUARED
Cosine squared theta = 1 + Sine squared theta
Yes. I assume you mean (x2 + y2) / (a2 + b2) = 1. Set all the variables to the same value - for example, all equal to one - and you have a valid solution.
(x - i)(x + i) where i is the imaginary square root of negative one
