Question

(3a−36)/ (12b−ab)
reduce

Answer 1

Hello there! :) :D

Answer:

$-\frac{3}{b}$

*The answer must have a fraction.*

Step-by-step explanation:

Lesson: Using properties to simplify expression.

Distributive property: a(b+c)=ab+ac

First, you had to factor by equation.

$3a-36=3(a-12)$

$\frac{3(a-12)}{12b-ab}$

Then, you factor out by the common term of b.

$\frac{3(a-12)}{b(-a+12)}$

You can also cancel by the common factor of a-12.

$\frac{3(a-12)}{b(-a+12)}=-\frac{3}{b}$

Hope this helps!

Thanks!
