Solve the following quadratic equation by factorization:

`sqrt(6)x^2 - 4x - 2sqrt(6) = 0`

Solve of the following equations, giving answer up to two decimal places.

3x² – x – 7 =0

Solve:

`(x/(x + 2))^2 - 7(x/(x + 2)) + 12 = 0; x != -2`

Solve : x² – 11x – 12 =0; when x ∈ N

Solve x² – 4x – 12 =0; when x ∈ I

Solve  2x² – 9x + 10 =0; when x ∈ Q

Solve:

(a + b)²x² – (a + b)x – 6 = 0; a + b ≠ 0

Solve:

`1/p + 1/q + 1/x = 1/(x + p + q)`

Solve:

x(x + 1) + (x + 2)(x + 3) = 42

Solve:

`1/(x + 1) - 2/(x + 2) = 3/(x + 3) - 4/(x + 4)`
