Question

Assuming that no denominator equals zero, which is equivalent to? r^2-r-6/(r-2)(r-3)​

Answer 1

The given expression is $\dfrac{ r^2-r-6}{(r-2)(r-3)}$. the option C $\dfrac{ (r+2)}{(r-2)}$is correct.

What is a simplification of an expression?

Usually, simplification involves proceeding with the pending operations in the expression.

Simplification usually involves making the expression simple and easy to use later.

The given expression is

$\dfrac{ r^2-r-6}{(r-2)(r-3)}$

By solving the numerator

$r^2-r-6\\\\r^2 - (3-2)r- 6\\\\(r-3)(r+2)$

Put the solution in the above equation

$\dfrac{ (r+2)(r-3)}{(r-2)(r-3)}$

$\dfrac{ (r+2)}{(r-2)}$

Therefore, the option C is correct.
