Answer:

Step-by-step explanation:
To solve a non-factorable quadratic equation in the form of
, you need to use the quadratic formula where
:




Because of the
sign, quadratic equations always have two solutions, whether both are real, only one is real, or both are complex (in the form of
where
is the real part and
is the imaginary part where
). In this case, because the discriminant is positive (defined as
), then there are 2 real solutions.
The solutions are thus 
Answer:
x-3
Step-by-step explanation:
f(x) = 3x-2
g(x) = 2x + 1
(f-g)(x) = 3x-2 - ( 2x+1)
Distribute the minus sign
=3x-2 -2x-1
Combine like terms
= 3x-2x -2-1
=x-3
