Complex Numbers and the Quadratic Function
Which of the following statements are true? Check all that apply.
The standard form for a complex number is
a
+
b
i
\displaystyle {a}+{b}{i}
a
+
b
i
where a and b are real numbers
i
2
=
−
1
\displaystyle {i}^{{2}}=\sqrt{{-{1}}}
i
2
=
−
1
Complex numbers are an extension of the real number system
i
=
−
1
\displaystyle {i}=\sqrt{{-{1}}}
i
=
−
1
If evaluating the discriminant of the Quadratic Formula (
b
2
−
4
a
c
\displaystyle {b}^{{2}}-{4}{a}{c}
b
2
−
4
a
c
) results in a negative number, then there will be no Real Number Solution to the problem
