Step-by-step explanation: The values for a, b, and c come from the
coefficients on our 3 terms in the trinomial.
The value for a comes from the coefficient
on the x² term which in this case is 2.
So we say that a = 2.
The value for b comes from the coefficient
on the x term which in this case is -6.
So we say that b = -6.
The value of c comes from the
constant term which in this case is -4.
So we say that c = -4.
