Expression: 3(x - 5) = 21
= 3x - 15 = 21
= 3x = 21 + 15
= 3x = 36
= x = 36/3
= x = 12
In short, Your Answer would be: 12
Hope this helps!

Hi!
You know that if f(p) = 0, then (x-p) is a factor of the polynomial f(x)
Then, f(3)=0 is the case p=0, son the factor is (x-3)
Answer: Since we are told that f(3) = 0, we know that (x-3) is a factor.
