Answer:
(7x+5)(x-1)
Step-by-step explanation:
Factor the following:
7 x^2 - 2 x - 5
Factor the quadratic 7 x^2 - 2 x - 5. The coefficient of x^2 is 7 and the constant term is -5. The product of 7 and -5 is -35. The factors of -35 which sum to -2 are 5 and -7. So 7 x^2 - 2 x - 5 = 7 x^2 - 7 x + 5 x - 5 = x (7 x + 5) - (7 x + 5):
x (7 x + 5) - (7 x + 5)
Factor 7 x + 5 from x (7 x + 5) - (7 x + 5):
