7 is the prime factor of 210
Step-by-step explanation:
First, let's move the 
to the right-hand side so we can determine what constant we'll need on the left-hand side to complete the square:
From here, since the coefficient of the 
term is 
, we know the square will be 
(since 
it's half of ).
To complete this square, we will need to add 
to both sides of the equation:
Now we can take the square root of both sides to figure out the solutions to :
I assumed you meant red instead of wet.
To calculate this, multiply 28% (which is the same as .28) times 300.
300 x .28 = 84
