Answer:
y = 2(x-5)(x+2)
Step-by-step explanation:
First make points out of the number!
(5,0), (-2,0), and (0,-20)
Plug it into this, p and q being the roots
y=a(x-p)(x-q) ---> y=a(x-5)(x+2)
Now plug in x and y from our y-intercept
-20 = a(0-5)(0+2) --> -20 = -10a ---> 2 = a
Now plug in "a" in orginal equation
y = 2(x-5)(x+2)
