The quadratic formula is -b plus minus the square root of b^2-4ac all over 2a.
Here, a=1, b=13, and c=30.

Answer:
y = 
Step-by-step explanation:
In order to get <em>y</em> by itself, we need to pull <em>y</em> out of 1 and <em>m </em>on the right side.
b = y(1 - m) since y(1 - m) is the same as y - my.
Once we have pulled <em>y</em> out of 1 and m, we can divide both sides by 1 - m
= 
We can cancel out the 1 - m on the right side since (1 - m) / (1 - m) = 1
Finally we get our answer:
= y
This is the same as y =
