How does the zero product property you find the x-intercept of y = x² - x - 12?

You set everything to 0, so when u do that all u need to do is FOIL to find the x-intercept, meaning whatever x is equal to.

We are given with the function y = x² - x - 12 and is asked to find the x-intercept applying the zero property. The x-intercept is obtained when y = 0. Hence, 

 y = x² - x - 12 = 0
 (x-4) (x+3) = 0
 Using zero property, we equate the two factors to zero

(x-4) = 0
x = 4
 (x+3) = 0
x=3

the zero property help find the solution set or y-intercept of the function

The answer would be c

I’m pretty sure the * means multiplication. so, if you multiply 5*1, it would equal 5. they are basically are-writing 5x1 as 5*1. so they would be… 5 10152025303540455055
