Answer:
You can use the basic multipication as an infrence
Answer:
A
Step-by-step explanation:
i just had this problem
When a zero of a function does not cross the x-axis but touches it, this means that the zero is a "double root". It has two of the same factor (x - 4)^2 and two of the same zeros, x = 4 and x = 4
f(x) = x^2 - 8x + 16 would be the function with a double root at 4
Answer:
3.6 is your Answer.
Step-by-step explanation:
Factor to find the roots.
(x+5)(x-1)=0
Proof:
5-1=4
5*-1=-5
Then apply the Zero Product Property.
(x+5)=0
x=-5
(x-1)=0
x=1
Roots: x=-5, x=1
