2x+3x=?

The function f(x)=2-3x+3x^(2)-x^(3), x in R is

The LCM of x^2 – 3x +2 and x^3 – 2x^2 – 3x is :

Simplify: (x^3-2x^2+3x-4)(x-1)-\ (2x-3)(x^2-x+1)

(x+3)/(2x+3)=(x+1)/(3x+2)

Check whether the following are quadratic equations : (1) (x-2)^(2)+1=2x-3 (2) x(x+1)=8=(x+2)(x-2) (3) x(2x+3)=x^(2)+1 (4) (x+2)^(3) = x^(3)-4

Test whether the following function f(x)=2-3x+3x^(2)-x^(3), x in R is increasing or decreasing.

Test whether the following funtions are increasing or decreasing : f(x)=2-3x+3x^(2)-x^(3), x in R .
