Answer:

The factors of the 7x² - 12x - 4 = 0 are (7x + 2)(x -2) .

Option (b) is correct i.e none of the above .

Step-by-step explanation:

As the expression given in the question.

7x² - 12x - 4 = 0

7x² - 14x + 2x - 4 = 0

7x (x - 2) + 2(x - 2) = 0

(7x + 2)(x -2) = 0

Thus the factors of the 7x² - 12x - 4 = 0 are (7x + 2)(x -2) .

Option (b) is correct i.e none of the above .
