Answer:
the answer is 4 playlists.
Step-by-step explanation:
F(x) = -9x^2 + 7x + 2
Factorising we get:
f(x) = (x + 1) (-9x + 2)
The solutions are x = -1 and 2/9ths
Work: k^2+kf-2f^2
Factor
(K+2f)(k-f)
Answer: (k+2f)(k-f)
Check your work:
K+2f k-f
K^2+2kf-kf-2f^2
K^2+kf-2f^2
The answer is correct
See image below it keeps going .
Amount - A, Rate - r, Principal - P, Interest - I, Time - t
