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
