Question

divide : 15(y+3)(y^2 -16) by 5(y^2-16)​

Answer 1

Question :

Divide

$15(y + 3)( {y}^{2} - 16) \div 5( {y}^{2} - 16)$

Answer :

We can write this question in this way -:

$\frac{15(y + 3)( {y}^{2} - 16) }{ 5( {y}^{2} - 16) }$

Now, we can cut (y² - 16) because it is common in both numerator and denominator.

$= \frac{15(y + 3)}{5}$

Now, we can see that 15 is divisible by 5, so

$= 3(y + 3)$

Now, through multiply we get our answer.

$= 3y +9$
