It equals 0. * * * * * Unless the question is (-x)2 + (+x)2. In that case, the answer is 2x2
3
'x' is +4 or -4 .
10 to the second power (102) is the same as 10 x 10, which equals 100.
If: y2+x2 = 52 Then: x2 = 52-y2 Their values could be: x = 3 and y = 4

sorry I mean equals x
If x^2 = 121 then the value of x is 11
'x' is +4 or -4 .
10 to the second power (102) is the same as 10 x 10, which equals 100.
x = 25^2 = 25*25 = 625.
If: y2+x2 = 52 Then: x2 = 52-y2 Their values could be: x = 3 and y = 4
62 = 6 x 6 = 36
That's the same as x3 times x3 which equals x6
x = +11 or -11
The vertex is the origin, (0,0).
