Answer:
(f-g)(x)
= -x^2 - 2x + 2
Step-by-step explanation:
(f-g)(x) means
f(x) - g(x)
= x - 2 - (x^2+3x-4)
distribute the subtraction to all three of the last terms.
= x - 2 - x^2 - 3x + 4
combine like terms
= -x^2 - 2x + 2
Remember that (a-b)(a+b)=a²-b²
and (imaginary number)²=real
so if we have a+bi, then a-bi is the conguate because (a+bi)(a-bi)=a²+b²
if the complex number is a+bi the conjucate is a-bi
Answer:
