Help please I have no idea what im doing and need these answers asap! Directions: Solve each question by completing the square. Simplify all irrational solutions.

1. x^2 - 2x - 4 = 0
2. x^2 + 16x + 46 = 0
3. x^2 + 7x + 7 = 66 - x
4. x^2 - 2 = 6x - 3

Directions: Solve each quadratic equation by completing the square. Simplfy all irrational solutions.

1. x^2 - 20x + 19 = 0
2. x^2 - 6x - 16 = 0
3. x^2 + 14c + 32 = -8
4. x^2 + 4x + 14 = 46
5. x^2 + 8x - 12 = 21
6. x^2 + 41 = 12x + 9
7. x^2 + 10x + 39 = 23
8. x^2 - x - 22 = x - 7
9. x^2 = 8x - 4
10. x^2 - 16x + 74 = 2x
11. x^2 + 12 = 38 - 16x
12. x^2 - 4x - = 21​
