When simplifying a^2+3a over a^3-2a^2-15a, what are the term(s) that can be cancelled

a(a+3) are the terms which can be cancelled.

Step-by-step explanation:

In this question if we factorize both the expressions then we can get the common factors which can be cancelled.

So first we factorize a²+3a = a( a+3 )

Now the second expression

⇒

⇒

⇒

⇒

Now it is clear to us that factors a(a+3) are the common factors that can be cancelled.

a and (a+3)

Step-by-step explanation:

We have the following expression and we will simplify it and see which terms can be cancelled out:

Now factoring both the numerator and the denominator to get the like terms which can then be cancelled out.

and are the common terms so they are cancelled and we are left with .

the least common denominator is 40
