c=8 or c=2

Explanation:

c^2-10c+16=0

(c-8)(c-2)=0

c=8 or c=2

c^2-10c+16 is in the general form y=x^2+bx+c which can also be written as y=x^2+("sum of roots")x+("product of roots")

What does that mean?

Well it means that you need to find two numbers that when added together equals to 10 and when multiplied equals to 16.

C = 8 or C = 2

Explanation:

This a simple Monic quadratic.

c^2-10*c+16=0
Factorise to give:
(c-8)(c-2)=0
Using Null factor law:
c-8 = 0 =>c= 8
or
c-2 = 0 =>c=2
