Simplify completely quantity of x squared minus 15 x plus 36 all over 5 x minus 60.

OpenStudy (abbles):

\[(x^2 - 15x + 36 )/5x - 60\] Look about right?

OpenStudy (abbles):

First factor the top. Do you know how to factor quadratics?

OpenStudy (abbles):

(x - 3)(x - 12) is what you should get for the top. The bottom you can factor out the 5 to get 5(x - 12). Can you guess what to do next? Hint: look at the terms that match up in the numerator and denominator to see what you can cancel out.
