$\frac{a-b\}{a-9}$ - $a^{2}$
You asked:
Evaluate the expression: \(\frac{a - b}{a - 9} - {a}^{2}\)
MathBot Answer:
Evaluated
\(\displaystyle \frac{a - b}{a - 9} - {a}^{2} = - a^{2} + \frac{a - b}{a - 9} \)
Expanded
\[\frac{a - b}{a - 9} - {a}^{2} = - a^{2} + \frac{a}{a - 9} - \frac{b}{a - 9}\]
Factored
\[\frac{a - b}{a - 9} - {a}^{2} = - \frac{a^{3} - 9 a^{2} - a + b}{a - 9}\]
