Question 60826
4/(x + 3) + 7/(x^2 - 3x + 9) = 108/(x^3 + 27)
4/(x + 3) + 7/(x^2 - 3x + 9) = 108/((x + 3)(x^2 - 3x + 9))
4((x + 3)(x^2 - 3x + 9))/(x + 3) + 7((x + 3)(x^2 - 3x + 9))/(x^2 - 3x + 9) = 108((x + 3)(x^2 - 3x + 9))/((x + 3)(x^2 - 3x + 9))
4(x^2 - 3x + 9) + 7(x + 3) = 108
4x^2 - 12x + 36 + 7x + 21 = 108
4x^2 - 6x - 51 = 0

{{{graph(300,300,-10,10,-10,10,4/(x + 3) + 7/(x^2 - 3x + 9),108/(x^3 + 27))}}}
They are relatively the same.
