Question

Solve: 4/x^2+5x+6 -3/x+3 =1/2

Answer 1

Answer:

0 =  x^3 +14x^2 + 43x + 48

Step-by-step explanation:

4/x^2+5x+6 -3/x+3 =1/2

by cross multiplying;

-11x - 3x^2 - 15 / x^3 + 8x^2 + 21x + 18 = 1/2

again cross multiply;

-6x^2 -22x -30 = x^3 + 8x^2 + 21x + 18

-x^3 -14x^2 -43x - 48= 0

0 = x^3 +14x^2 + 43x + 48

idk how to solve the remaining
