Answer:
Step-by-step explanation:
If you want to factor this, you have to use the quadratic formula to do so.

For us, it looks like this:

which simplifies to

Since it breaks every mathematical rule to have a negative number under an even index radical, we have to deal with that using the imaginary "i". You should know at this point that 
so we will do a rewrite on that equation above:

which simplifies further to

This is the answer but we can separate it into its proper standard form which is
and 
Answer:
x = 26, y = 11
Step-by-step explanation:
opposite sides are equal
Answer:
12
Step-by-step explanation:
Then the -12 and +12 will cancel out, so you're left with a clean isolated r on the left:
r -12 +12 = 19 + 12
r = 31
Answer:
Option (A)
Step-by-step explanation:
By satisfying the equation of a function 'f' by each coordinates given in the options we can get the point which lies on the graph of f(x) = 
Option (A). (1, 10)
f(1) = 
10 = 10
True.
Therefore, point (1, 10) lies on the graph.
Option (B). (0, 10)
f(0) = 
10 = 2
Not true.
Therefore, point (0, 10) doesn't lie on the graph.
Option (C). (10, 1)
f(10) = 
1 = 19531250
Not true.
Therefore, point (10, 1) doesn't lie on the graph.
Option (D). (0, 0)
f(0) = 
0 = 2
Not True.
Point (0, 0) doesn't lie on the graph.
Option (A) will be the answer.
