use factoring and the zero-product property to solve the following problem x^2-x-2=4

OpenStudy (anonymous):

x= what?

OpenStudy (anonymous):

it doesn't say

OpenStudy (thephysicsman):

that's easy just make sure you have to set that equation equal to zero \[x^2-x-2-4 = 0 \]

OpenStudy (thephysicsman):

then simplify and factor. can you do this? \[x^2-x-6 = 0\]

OpenStudy (thephysicsman):

@link,zoro

im looking in my text book give me a sec

OpenStudy (thephysicsman):

do you see that last term -6?

OpenStudy (mathmale):

Think: What pairs of numbers are integer factors of -6? Write them out. for example: (2)(-3). What other pairs can you come up with? which pair adds up to -1 (which is the coefficient of the middle term of your quadratic).
