What are the solutions of the equation? y=-7(x-3)(x+4)

Mathematics
1 answer:
Shkiper50 [21]3 years ago
3 0

Answer:

{-4, 3}

Step-by-step explanation:

To find "solutions," you must set this function equal to zero:

y = -7(x - 3)(x + 4) = 0

and then set each factor equal to 0 separately and solve each resulting equation for x:

x - 3 = 0 yields x = 3, and

x + 4 = 0 yields x = -4
