If 2x2 = 250 then x2 = 250/2 = 125
So x = sqrt(125) = 5*sqrt(5) = +/- 5*2.236 = + or - 11.180

The solutions are: x = 4, y = 2 and x = -4, y = -2
So what is the question?
2.645 squared equals 7. Save --------- Unclear what you're asking: If x=7, then x^2 (that is, "x squared") equals 49. or If x^2=7, then x equals the square root of 7, or about 2.64575

(2, -2)
If I have this correct you are asking x^2 + 10^2 = 12^2 Then x=6.633249507108
2 x cosine squared x -1 which also equals cos (2x)

√8 = 2√2 ≈ 2.828
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
x^2 +9 =x^2 -9 9=-9 No solution
