Answer:
Option 4th is correct
x = 3, -1
Step-by-step explanation:
Given the equation:
To find the zeroes of f(x).
Set f(x) = 0
then;
Factorize this equations:
Split the middle terms we have;
⇒
⇒
By zero product property we have;
x-3 = 0 and x+1 = 0
⇒x = 3 and x = -1
Therefore, the zeroes of the function f(x) are :
x = 3 and x = -1
9^2 - 6^2 = x^2
81- 36=x^2
x^2 = 45
x = √45
x= √5×3 ×3
x=3 √5
the answer is D
