|(x^(2)-5x+4)/(x^(2)-4)|<=1

Solve : abs((x^2-5x+4)/(x^2-4))le1

Solve the following: (sqrt(x^(2)-5x+6)+sqrt(x^(2)-5x+4))^((x)/(2))+(sqrt(x^(2)-5x+6)-sqrt(x^(2)-5x+4))^(x/2)=2^((x+4)/(4))

Express the following in the lowest terms. ((x-3)(x^(2)-5x+4))/((x-4)(x^(2)-2x-3)):

(x^(2)+4x)^(2)-5(x^(2)+4x)-y(x^(2)+4x)+5y

Evaluate the following limits : Lim_(x to oo )( sqrt(x^(2)+5x+4)-sqrt(x^(2)-3x+4))

Simplify ((2x+1)(x-2))/(x-4)-((2x^(2)-5x+2))/(x-4)

int(x^(2)+4x+4)/((x^(2)+5x+7)sqrt(x+2))dx
