Use the zero product property to determine the x-intercepts for the graph of the quadratic function 1. y= -x squared -7x-12
2. y= 3x squared +11x+10

1) x-intercepts are at -3 and -4

2) x-intercepts are at 5/3 and 2

Step-by-step explanation:

1) y = -x^2 - 7x - 12  is -(x + 3) (x + 4)

2) y = 3x^2 + 11x + 10  is (3x + 5) (x + 2)

unless if u could do my questions, if not i wouldn't want to
