Step-by-step explanation:
Completing the square gives

So we have to cancel the latter two terms out for the expression to always become a square (otherwise we are dealing with a square plus something else, which doesn't always result in a square), giving us our answer directly.
A literal equation<span> is, simply put, an equation that has a lot of letters or variables.
example :
A = bh
Lets solve it for b.
A = bh
A/h = bh / h
A/h = b
Now lets say we have equation in one variable like 10 = 5x
we can find x simply by, x = 10 / 5 = 2
The way of solving it similar. The difference is literal equation have more variables, you solve for certain variable in terms of another variables while in one variable you get the direct number.
