first you would put the expression in a fraction for
180/460
you already know that the both numbers are divisible by 2
- so the answer would be 90/230 but we are still no done because these values are divisible by three
the rule to prove that the number is divisible by three is when you add the digits of the number for example 333. 3+3+3=9 and nine is divisible by nine
THE ANSWER IS:::::::: 90/230
The solution should be x=5
If f(x) = 0 then it is a root
x + 3 = 0
x=-3
f(-3) = (-3)^4 + 10(-3)^3 + 23(-3)^2 - 34(-3) - 120 = 0
x - 2 = 0
x=2
f(2) = (2)^4 + 10(2)^3 + 23(2)^2 - 34(2) - 120 = 0
