The x intercept(s) occur when f(x) = 0
so we have (x - 3)( x^2 - 25) = 0
So x - 3 = zero and x = therefore = 3.
The answer is the third choice 3
Answer:
Subtract 5 over 6.
24 over 6 is 4
Step-by-step explanation:
The equation is y^2=16x and the directrix is x=-4
Answer:
(x-7)(x+7)
Step-by-step explanation:
x^2 -49
This is the difference of squares
x^2 -7^2
We know that a^2 -b^2 = (a-b)(a+b)
(x-7)(x+7)
Answer:
471.24
