01 Use the quadratic formula to solve each equation. List every distinct solution.

Use exact answers: x^2 for powers, sqrt(2) for radicals and i for imaginary numbers. Separate solutions with commas.

1. Use the quadratic formula x^2-9x+20 = 0 over the real numbers. List all distinct solutions, or write no solution.

2. Use the quadratic formula x^2+6x+9 = 0 over the real numbers. List all distinct solutions, or write no solution.

3. Use the quadratic formula x^2-12x+33 = 0 over the real numbers. List all distinct solutions, or write no solution.

4. Use the quadratic formula x^2+2x+37 = 0 over the real numbers. List all distinct solutions, or write no solution.

5. Use the quadratic formula 30x^2-18x-12 = 0 over the real numbers. List all distinct solutions, or write no solution.

6. Use the quadratic formula 4x^2+24x+33 = 0 over the real numbers. List all distinct solutions, or write no solution.

7. Use the quadratic formula x^2+2x-24 = 0 over the real numbers. List all distinct solutions, or write no solution.

8. Use the quadratic formula x^2+10x+25 = 0 over the real numbers. List all distinct solutions, or write no solution.
