Yes. When the function f(x) = x3 – 75x + 250 is divided by x + 10, the remainder is zero. Therefore, x + 10 is a factor of f(x) = x3 – 75x + 250.
According to the remainder theorem when f(x) is divided by (x+a) the remainder is f(-a).
In this case,
f(x)=x^3-75x+250
(x+a)=(x+10)
Therefore, the remainder f(-a)=f(-10)
=x^3-75x+250
=(-10)^3-(75*-10)+250
=-1000+750+250
=1000-1000
=0.
The remainder is 0. So, (x+10) is a factor of x^3-75x+250.
So 1st make it equal to zero
x^2+4x-12
(x+6)(x-2)
so
x=-6 or 2 is the correct answer
Answer:
148x
Step-by-step explanation:
12x^2 + 4x
144x + 4x
148x
I think this is correct? But hopefully this helped :)
Answer:
the mean of a set is the average of the numbers in that set. How you get the mean is you add up all the numbers then you divide by how many numbers are in the set.
Step-by-step explanation:
example is 1,2,3,4,5,6,7
the mean of this set is 4
