HI

Sagemath 9.1 notebook ,OS :Ubuntu 18.04

what should i add or precise, so that SageMath solve this equation ?:

assume(x,'real')
solve (sqrt(-x^2 + 1)==-4/3*x - 25/36,x)

output :[x == -3/4*sqrt(-x^2 + 1) - 25/48] ?

Try

sage: solve(sqrt(-x^2 + 1)==-4/3*x - 25/36, x, to_poly_solve=True)
[x == -1/20*sqrt(119) - 1/3]

or

sage: solve(sqrt(-x^2 + 1)==-4/3*x - 25/36, x, algorithm='sympy')
[x == -1/20*sqrt(119) - 1/3]
