f(x)=-(1)/(3)x^(3)+5x^(2)+12

3^(x-1)+3^(x)-12=0

f(x)=3x^(3)+x^(2)-20x+12,g(x)=3x-2

The coefficient of x^(4) in the expansion of (x^(2)+(1)/(x^(3)))^(12) is , ((12)/(4)) ([12],[6]) ([12],[7]) ([12],[9])

(-12x+x+3)/(15x+3)=(99-4+11x)/(99x+12)

p(x) = 12/(x-3), p(3) = ……………….

lim_(x to 2) (x^(3) + x^(2) + 4x + 12)/(x^(3) - 3x + 2) is equal to
