" 42."(x^(2))/(x^(2)+6x+12)

int(x^(2))/(x^(2)+6x+12)dx

int(x^(2))/(x^(2)+6x-12)dx

int (x^(2)dx)/(x^(2)+6x+12)

int(x^2)/(x^2+6x-12)dx

(x^(2)+7x+12)/(x^(2)+8x+15)times(x^(2)+5x)/(x^(2)+6x+8)=____ .

The set of real values of x satisfying log_((1)/(2))(x^(2)-6x+12)>=-2

Integrate: int((5x^(2)-12)dx)/((x^(2)-6x+13)^(2))

6x^(2)+x-12=0

If x^(2) + ((1)/(x^(2))) =1 , then what is the value of x^(48) + x^(42) + x^(36) + x^(30) + x^(24) + x^(18) + x^(12) + x^(6) + 1 ?
