Answer:

2y² + 9

---------------

15y³

Step-by-step explanation:

Start by identifying the LCD, and then change each fraction so that its denominator is the LCD.

Here the LCD is 15y³, which is evenly divisible by 15y and 5y³.

Focus now on the first fraction: 2 / (15y). Multiplying numerator and denominator of this fraction by y² results in

y²·2 2y²

--------- → ----------

y²·15y 15y³ ←This is the correct LCD

Multiplying numerator and denominator of the second fraction by 3 results in:

3·3 9

------------ → ---------

3·5y³ 15y³ ←This is the correct LCD

So now those two original terms look like:

2y² 9

--------- + --------

15y³ 15y³

and this can be written in simpler form as:

2y² + 9

---------------

15y³

Assignment: $\bold{Factor \ 4u^2-28u+49}$

<><><><><>

Answer: $\boxed{\bold{\left(2u-7\right)^2}}$

<><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><>

[ Step One ] Rewrite $\bold{4u^2-28u+49}$

$\bold{\left(2u\right)^2-2\cdot \:2u\cdot \:7+7^2}$

[ Step Two ] Apply perfect square formula

Note: Perfect Square Formula: $\bold{\left(a-b\right)^2=a^2-2ab+b^2}$

$\bold{a=2u,\:b=7}$

$\bold{\left(2u-7\right)^2}$
