Thus, x = -3/2 or x = -1.

3. Solve: x² + 2√2x – 6 = 0

Solution: Using the quadratic formula:

x = [-2√2 ± √((2√2)² - 4×1×(-6))]/(2×1)

= [-2√2 ± √(8 + 24)]/2

= [-2√2 ± √32]/2

= [-2√2 ± 4√2]/2

Thus, x = (2√2)/2 = √2 or x = (-6√2)/2 = -3√2.

4. Solve: 3x² – 5x + 2 = 0

Solution: Factorizing:

3x² – 3x – 2x + 2 = 0

(3x – 2)(x – 1) = 0

Thus, x = 2/3 or x = 1.

5. Find the roots: x² – 4√3x + 12 = 0

Solution: Using the quadratic formula:

x = [-(-4√3) ± √((-4√3)² - 4×1×12)]/2

= [4√3 ± √(48 - 48)]/2

= (4√3 ± 0)/2

Thus, x = (4√3)/2 = 2√3.

(Repeated root.)

6. Solve: 2x² – 3x – 2 = 0

Solution: Using the quadratic formula:

x = [-(-3) ± √((-3)² - 4×2×(-2))]/(2×2)

= [3 ± √(9 + 16)]/4

= [3 ± √25]/4

Thus, x = (3 + 5)/4 = 2 or x = (3 – 5)/4 = -1/2.

7. Solve: x² – 7x + 10 = 0

Solution: Factorizing:

x² – 5x – 2x + 10 = 0

 (x – 5)(x – 2) = 0

Thus, x = 5 or x = 2.

8. Solve: 4x² – 12x + 9 = 0

Solution: Recognize it as a perfect square

(2x – 3)² = 0

Thus, 2x – 3 = 0 

x = 3/2.

9. Find the roots: x² + 5x + 6 = 0

Solution: Factorizing:

x² + 3x + 2x + 6 = 0

(x + 3)(x + 2) = 0

Thus, x = -3 or x = -2.

10. Solve: x² – 2x – 8 = 0

Solution: Factorizing:

x² – 4x + 2x – 8 = 0

(x – 4)(x + 2) = 0

Thus, x = 4 or x = -2.

11. Solve: 6x² – x – 2 = 0

Solution: Using factorization:

6x² – 4x + 3x – 2 = 0

 (3x – 2)(2x + 1) = 0

Thus,

x = 2/3 or x = -1/2.

12. Solve: 7x² + 14x + 7 = 0

Solution: Recognizing perfect square:

7(x² + 2x + 1) = 0

= 7(x + 1)² = 0

Thus,

x + 1 = 0 ⇒ x = -1.
