For binomials, follow the rule FOIL (first, outside, inside, last.)
4x^2 + -8x + - 8x + 16
4x^2 – 16x + 16

Answer:
64
Step-by-step explanation:
So here you're just completing the square. the equation you gave is simply: 
where c is the unknown value we're solving for. Whenever you complete the square, you add (b/2)^2
The reason for this, is because whenever you write a binomial as a perfect square it's in the form: 
and this binomial expands out to become: 
If we write the second term of the binomial as b/2 we get:
which simplifies to:
and as you can see the last term is (b/2)^2, which is why we need to add that part for it to be a perfect square.
So we would need to add (16/2)^2 = 8^2 = 64
This way, we can express it as a perfect square binomial: 
which expands out to: 
If 1 pt = 1/72 inch
and Esmeralda wants her text to be 1/72 inch tall
Surely, she should use 1 pt as her font size?
