The way to find the factores is by seeking the polonomial's roots, or zeros!
To find the roots, we set the polinomial equation to zero:
x^2+16y^2=0
Then we solve this equation:
x^2=-16y^2
This is only true, if x=y=0.

An exterior angle is equal to the sum of the 2 non adjacent angles. In this case
100 = x + 70 Subtract 70
x = 100 - 70
x = 30
