Hello, we need to see it as a difference of two squares as we know that for all a and b real numbers

So, here

Voila !
Thank you
Hey there!
ANSWER: 
EXPLANATION:
To find the answer to your question, you will need to add.

First, multiply the denominator.

So the denominator will be 20.

Now multiply 4 bu 2.

If you want to get the numerator, add what you got after multiply.

The numerator is 23. So now let's complete the fraction.

This is your answer!
Hope this helps!

Answer:
x= 10, x=1
Step-by-step explanation:
(x-1)(x-10)=0
then solve for x
X = 4(180 - x)
x = 720 - 4x
4x + x = 720
5x = 720
x = 720/5
x = 144
180 - x =
180 - 144 =
36
the measure of the angle is 144...the measure of its supplement is 36
