Question

The method used to factor trinomials of the form ax^2+bx+c can also be used to factor binomials of the form px^2+q by realizing that, in this case, _____. A. a = 0 B. b = 0 C. c = 0 D. x = 0

Answer 1

I think the best answer to your question is letter B. B=0. in the first trinomial factor of a form ax^2+bx+c is where the both variable values are not zero or having a positive or negative value which could make it possible to be factor off. While the second function px^2+q is the data that should be assigned into B is canceled out because its value is Zero.
