To express the expression \(2 + \checkmark - 9\) as a complex number, we need to interpret \( \checkmark \). Typically, a checkmark does not have a mathematical value and could represent a variable or unknown value.
Assuming \( \checkmark \) represents a variable \( x \), we can rewrite the expression:
\[ 2 + x - 9 = (2 - 9) + x = -7 + x \]
Thus, in terms of a complex number, we can express it as:
\[ -7 + x i \]
Where \( x \) is a real number (assuming \( \checkmark \) represents an imaginary component). Therefore, if \( \checkmark \) is not meant to represent a specific value, you would end up with a complex number representation in terms of \( x \):
\[ -7 + 0i + xi = -7 + xi \]
If there is a specific value or context for \( \checkmark \), please provide that for a more precise answer.
