" (i) "(5x-(1)/(x))^(2)+5(5x-(1)/(x))+6

(1)/(x^(2)-5x+6)>=(1)/(2)

(x^(2)+1)/(x^(2)-5x+6)

Determine the values of x satisfying the following equalities: (a) |(x-1)/(x+1)|=(x-1)/(x+1) (b) |x^(2)-5x+6|=-(x^(2)+-5x+6)

Add :5x^(2)-(1)/(3)x+(5)/(2),-(1)/(2)x^(2)+(1)/(2)x-(1)/(3) and -2x^(2)+(1)/(5)x-(1)/(6)

Simplify (x-3)/(x^(2)-x-6) + (2x-1)/(2x^(2) + 5x-3) - (2x +5)/(x^(2) + 5x +6)

The product of ((1)/(5)x^(2)-(1)/(6)y^(2)) and (5x^(2)+6y^(2)) is
