Question

Simplify and state the excluded values.
45x^2 - 27x over 63x^2 - 45x

Answer 1

\[\frac{ 45x^2-27x }{ 63x^2 - 45x }\]

first simplify both numerator and denominator (hint: 3 is a good start, but you have to do more than just 3)
2nd, cancel out the common factor for both top and bottom
and you get your answer
