Logarithms are exponents.



Remember the sum of the logs is the log of the product:



If the base is not specified, the base is assumed to be 10, hence using the definition of logarithms from above:



Anything raised to the 1 power is just that thing, hence:



Put the quadratic into standard form and solve. Hint: it factors.
