Answer:
= [tex]5x^{2}[/tex] - 12x- 11 + [tex]\frac{11x + 45}{x^2 + 3}[/tex]
Step-by-step explanation:
Using long division of polynomials tells us that the polynomial:
5x^4 - 12x^3 + 4x^2 - 25x + 12
can be divided by
x^2 + 3
to give us an answer of
[tex]5x^{2}[/tex] - 12x- 11 + [tex]\frac{11x + 45}{x^2 + 3}[/tex]
