x = +11 or -11
112 = 11 x 11 = 121
eleven 11 x 11 = 121 121 x 11 = 1331
Do you mean? X^2 - 121 = 0 add 121 to each side X^2 = 121 take square root of each side x = (+/-) 11
√121 = 11 → 11 × 11 = 121 Also: -11 × -11 = 121
x = +11 or -11
112 = 11 x 11 = 121
It equals 0. * * * * * Unless the question is (-x)2 + (+x)2. In that case, the answer is 2x2
1 x 121, 11 x 11, 121 x 1 = 121
Well, how about 11 x 11 = 121 ?11 x 11
X to the 2nd power is simply X squared, or X times X.

24.2 x 5 = 121
11 x 11 = 121
sorry I mean equals x
'x' is +4 or -4 .
x2 + 121y2 = x2 - (-121)y2 = x2 - (11iy)2 = (x - 11iy)(x + 11iy)
