Question 509261
They call it the "zero-product property" for a reason.


You should expand and simplify it first.


*[tex \LARGE x^2 - 3x + 2 = 30 \Rightarrow x^2 - 3x - 28 = 0]


This can be factored to


*[tex \LARGE (x-7)(x+4) = 0]


Now we can use the zero-product property and obtain x = 7 and x = -4 as our solutions.
