Daily puzzle

Find the positive root of x^2 - 3x - 10 = 0.

Expected output: 5 Timer: 00:00

Drag and drop the blocks until they represent a valid solution. The order shown below is intentionally mixed.

x = sp.symbols('x')
return max(roots)
expr = x**2 - 3 * x - 10
import sympy as sp
roots = sp.solve(expr, x)

Attempts: 0 No sandboxing—pure ordering logic Mock output only

Arrange the blocks, then tap Run to check.
