On dividing we get 69/2 or 34.5 as remainder.
In algebra, the factor theorem is a theorem linking factors and zeros of a polynomial. It is a special case of the polynomial remainder theorem. The factor theorem states that a polynomial f(x) has a factor if and only if f=0.
Long division is best suited for such expressions:-
On applying long division and factor theorem we get
2x²+7x-39 = (2x - 1/2)(x-7) + 69/2
Thus on dividing we get 69/2 or 34.5 as remainder.
