How do you determine whether x+2 is a factor of the polynomial #2x^3+2x^2-x-6#?
You divide using polynomial long division or synthetic division and if the remainder is 0 then it is a factor.
this division has a remainder of -12 so it is not a factor.
Just check if
We know that if a polynomial
We can use the Polynomial Remainder Theorem, which states when a polynomial,
We are dividing
We have a remainder, which means
Hope this helps!
