How to enter an exact answer
Use sqrt(5), 3/2 and x^2. For roots: -7, 4. For intervals: (-inf,2] U (5,inf), or 2 < x < 5. For no solutions: empty. For pairs: (1,3); (3,-1). Keep each pair together. For a formula, enter the expression only, such as (3*x+1)/(x-2). Use cbrt(x+8) for a real cube root and pi for π. A line needs a complete equation, for example 3*x+4*y=20; vertical lines such as x=3 are valid. Separate multiple equations with a semicolon. For coordinate maps, use the variables named in the label.
