Answer 1

Answer:

Step-by-step explanation:

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

3x^2 + x - 12x - 4 = 3x^2 + 6x - x - 2

-11x - 4 = 5x - 2

-11x - 5x - 4 + 2 = 0

-16x - 2 = 0 ---> (1)

We can take minus sign from (1) as it has only negative terms. Therefore, (1) becomes

- (16x + 2) = 0

16x + 2 = 0

This is the reason why 16x is not negative and 2 is positive.
