2 answers:
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 .
After simplifying you will get (7x+2)(x-2)=0. This means that the answer is
