Cross multiplication will help find the value of x

9*2=18
3*z=3z
Now we have :
3z=18
Divide both sides by 3 to isolate z
Final answer: z=6
If -5 is a root then f(x) is divisible by x + 5
The quotient from this division is 3x^2 -20x +12
Factoring this:-
= 3x^2 - 18x - 2x + 12
= 3x(x - 6) - 2(x - 6)
= (3x - 2)(x - 6)
So 2 more roots are 2/3 and 6
All the roots are -5 , 2/3 and 6. Answer
