In this Algebra 2 lesson, we work through a tough rational expression and simplify it step by step with clear reasoning at each stage.
Problem:
4 − (x − 3)/(9x² − 4) + 1/(2 − 3x)
We factor the denominators, rewrite the expression carefully, manage negatives, combine fractions, and simplify all the way down to the final answer:
(36x² − 4x − 15)/(9x² − 4)
