Answer 1

@Michele_Laino @ParthKohli @Nnesha can any of you help with this?

Answer 2

first statement:
here we have to simplify the right side, so I can write this:
\[{x^2} - 4x + 9 - \frac{{30}}{{x + 4}} = \frac{{\left( {{x^2} - 4x + 9} \right)\left( {x + 4} \right) - 30}}{{x + 4}} = ...?\]
please continue

Answer 3

am i simplifying all of what you wrote or only what's on the right side of he equal sign?

Answer 4
