To perform this check, you must use the following theorem: 
is a lower bound for the zeroes of 
if, when divide by 
, the quotient and the remainter alternate signs.
Since the long division yields the result
You can see that the signs don't alternate (the last two terms are positive). So, -1 is not a lower bound.
In fact, the actual roots of the polynomial are -3, -2, 1, 3, so as you can see there are roots smaller than -1.
Answer:
x = 50
Step-by-step explanation:
x/5 = 10
Multiply both sides of the equation by 5.
5(x/5) = 5(10)
x = 5(10)
x = 50
The value of x is 50.
