Is x + 10 a factor of the function f(x) = x3 − 75x + 250? Explain.

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.

No. When the function f(x) = x3 − 75x + 250 is divided by x + 10, the remainder is zero. Therefore, x + 10 is not a factor of f(x) = x3 − 75x + 250.

Okay, I worked it out and yes, it is a factor. Once you got x=-10, then you plug it into your formula. from there you can work it out like I did and get the answer. You can also input it into a scientific calcuator and figure it out that way. If you need any more help, go ahead and message me. Hope this helps. You can also but it into the box and divide it that way to find out. whichever way is better for you

Answer:

yes, When the function
f(x)=x^3-75x+250 is divided by x+10 , the remainder is zero.Therefore, x+10 is a factor of
f(x)=x^3-75x+250

Explanation:

We are given that


f(x)=x^3-75x+250

We have to find
x+10 is a factor of given function.

By remainder theorem


x+10=0


x=-10

Substitute x=-10

Then , we get


f(-10)=(-10)^3-75(-10)+250


f(-10)=-1000+750+250=0

Remainder=f(-10)=0

It means x+10 is factor of given function f(x) because when x+10 divides the f(x) then we get remainder=0.

Answer:yes, When the function
f(x)=x^3-75x+250 is divided by x+10 , the remainder is zero.Therefore, x+10 is a factor of
f(x)=x^3-75x+250
