Answer:
The correct answer is , Option D. (5x - 1)(x + 7)
Step-by-step explanation:
The given polynomial is,
5x(x + 7) - (7 +x) -----(1)
From this we can write,
5x(x + 7) - (x + 7) ----(2)
we can see that in equation (2) (x + 7) is common
Therefore we can write,
(x + 7)(5x - 1)
(5x - 1)(x + 7)
Therefore the correct answer is , Option D. (5x - 1)(x + 7)
