18x^2y-24xyz

Factorize the following expressions 18x^2y-24xyz

trace the following conics 9x^(2)-24xy+16y^(2)-18x-101y+19=0

Find the intervals in which the graphs of the following functions are concave or convex and locate the points of inflection : y = x^(4) +x^(3) -18x^(2) +24x-12 ,

The equation 12x^(2)+7xy-12y^(2)-18x+y+6=0 represents

Resolve into factors 3y(16z^2+x^2)+4z(x^2+9y^2)+x(9y^2+16z^2)+24xyz

Divide 24(x^(2)yz+xy^(2)z+xyz^(2))by8xyz' using both the methods.

If x + y + z = xyz , prove that x(1 -y^(2)) (1- z^(2))+ y(1- z^(2))(1- x^(2)) +z(1-x^(2)) (1- y^(2)) = 4xyz .
