Which of the following show the factored equivalent of f(x) = (2x2 +7x + 3)(x - 3) and its zeros?
a. f(x) = (x + 5)(x + 7)(x - 3); -5, -7, 3
b. f(x) = (x + 3)(2x + 1)(x - 3); -3, -0.5, 3
c. f(x) = (x + 5)(x + 7)(x - 3); 5, 7, -3
d. f(x) = (x + 3)(2x + 1)(x - 3); 3, 0.5, -3

the answer is c

hope this !

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
