I’m not sure what you mean by "sqrt-4x". Two common interpretations:

1) 3 + √(4x) = 19
- Isolate the root: √(4x) = 16
- Square both sides: 4x = 256
- Solve: x = 64
- Check domain: x ≥ 0, and x = 64 is valid.

2) 3 + √(−4x) = 19
- Isolate the root: √(−4x) = 16
- Square both sides: −4x = 256
- Solve: x = −64
- Check domain: −4x ≥ 0 ⇒ x ≤ 0, and x = −64 is valid.

Tell me which interpretation you meant (or paste the expression with parentheses), and I’ll confirm.
